Rowlf the Dog

Rowlf the Dog was the first Muppet to reach national stardom as a cast member of The Jimmy Dean Show from 1963 to 1966. He later went on to serve as the resident piano player on The Muppet Show, where he also played the silly surgeon Dr. Bob in the recurring sketch "Veterinarian's Hospital".

The Muppet Movie
Rowlf was prominently featured in The Muppet Movie as a piano player at The Terrace Restaurant, where he first meets Kermit. When Kermit is down, Rowlf share his motto in life, a motto even he can't follow - "stay away from women." The two sing "I Hope That Somethin' Better Comes Along". An original draft of the script describes the song as "a sad/funny little duet based on the old 'can't live with 'em, can't live without 'em' theme, designed to allow for some good harmony howling from Rowlf."

The song featured a rare pairing of characters, as Jim Henson virtually performed a duet with himself. In order to achieve the effect, the vocals of the two characters were recorded separately by Henson and then combined.

Rowlf soon joined Kermit and the rest of the gang on their way to Hollywood. Before joining the Muppets, Rowlf's life was simple - he lived alone, would "go to work, come home, read a book, have a couple of beers, take [himself] for a walk and go to bed." While in the desert, Rowlf played harmonica as Gonzo sang "I'm Going to Go Back There Someday" (while Fozzie played ukulele). Rowlf served as the film's cameraman in the finale, as the Muppets prepare to shoot their movie.

Rowlf appeared in the promotional special The Muppets Go Hollywood, accompanying Johnny Mathis as he sang "Never Before, Never Again".

The Muppets
Rowlf appeared as one of the main characters in The Muppets, again performed by Barretta. He rejoins the Muppets to help put on the telethon to save the Muppet Studios. At one point, he laments being excluded from the montage gathering the Muppets; a clip is then shown of Kermit, Walter, Gary and Mary asking Rowlf, who is laying in a hammock, if he wants to join the reunion, to which he replies "Okay."

Rowlf returns to his role as the pianist for the Muppet Theater orchestra, playing for both "The Muppet Show Theme" and the musical finale of "Life's a Happy Song". Rowlf also performs in The Muppet Telethon as a member of the Muppet Barbershop Quartet, along with Link Hogthrob, Sam Eagle and Beaker, singing "Smells Like Teen Spirit" while shaving Jack Black.

A sinister doppelgänger of Rowlf, named Roowlf, appears in the film as a member of The Moopets.

Rowlf starred in the Muppets' promotional tie-in commercial for Alamo Rent a Car, and Yamaha Entertainment's Muppets sweepstake. Rowlf was also featured in a series of promotional posters spoofing The Twilight Saga: Breaking Dawn as WereRowlf. He also appeared in the OK Go music video for "The Muppet Show Theme Song."

According to an interview with Yamaha All Access, Rowlf considers Jason Segel "a fine piano player. During the movie, we jammed together between takes. Boogie-woogie! Jason plays a mean boogie, and my woogie is still wagging, even if I say so myself.

Rowlf appeared in the opening of Jim Henson's Musical World, both in video from his performance with Jimmy Dean at Carnegie Hall in 1965, and in the actual hall. He lamented about the fact that it took Carnegie Hall 47 years to invite him back. Rowlf also sang "I Never Harmed an Onion" at the Just for Laughs show in July 2012.

Post-Henson
After the death of Jim Henson, Rowlf continued to appear in Muppet productions, silently (and usually briefly). A rumor arose that the character would be permanently silent as a sign of respect to Jim. As Brian Henson commented on in the audio commentary for The Muppet Christmas Carol, Rowlf continued to appear as a tribute to the character and Henson's legacy. Still, he wasn't immediately recast and kept in the forefront like Kermit, because at the time, the Muppeteers didn't feel there was a suitable and appropriate performer for the task.

Rowlf was featured silently in The Muppet Christmas Carol (playing piano at Fozziwig's party) and Muppet Treasure Island (as a patron of The Admiral Benbow Inn).

Bill Barretta starting taking on the character in 1996 and gradually transitioned into the role. Although Rowlf only appeared in one episode of Muppets Tonight, he uttered his first words since Jim's passing in episode 102; while playing piano during the closing number, Rowlf exclaims "Oh yeah!" He also appeared in Muppets from Space as a resident of the Muppet Boarding House and, at one point, muttered an audible "Oogh!".

Rowlf had several lines of dialogue, a first since Henson's passing, in The Muppet Show Live in 2001 and also spoke 2 lines of dialogue ("Hey, Kermit!" and "Yeah! Heh, heh. Oh!") in It's a Very Merry Muppet Christmas Movie in 2002.

Rowlf appeared in the "Keep Fishin" music video for rock band Weezer. Although he's only briefly seen (one can hear him muttering "Good job, River" and "Yeah"), Rowlf had a more prominent role in the behind the scenes making-of special that accompanied it, Weezer and the Muppets Go Fishin'.

In 2005, Rowlf had a 190-word monologue in the second episode of Statler and Waldorf: From the Balcony. Additionally, Bill Barretta recorded the vocals as Rowlf singing "The Christmas Party Sing-Along" for the 2006 album A Green and Red Christmas.

For The Muppets' Wizard of Oz, in the extended interview with Quentin Tarantino, Tarantino commented on how he was disappointed that Rowlf didn't appear much in the movie. Pepe explained this by saying Rowlf was in a car accident and broke his tail and preferred to not do too many scenes.

Rowlf was prominently featured in a pair of online videos in 2008, "Rolling with the Skateboarding Dog" (where Rizzo comments on his age) and "Skateboarding Dog Gets Served" (where Rowlf tries to show up Tyson, a skateboarding bulldog).

Rowlf made a rare live appearance on Late Night with Jimmy Fallon, where he sings the "8 maids a-milking" line for The Twelve Days of Christmas number while playing keyboards with the Roots.

Rowlf has a speaking cameo in the "Game Day" episode of The Muppets Kitchen with Cat Cora. Referencing his absence in recent years, he comments "It's a small part, but times are ruff."

Rowlf also had a semi-prominent role in The Muppets. He was also notably featured in the OK Go music video for "The Muppet Show Theme Song".
