The Flyin' Fishmonger

The Flyin' Fishmonger is the theme song specially commissioned by Reginald Fletcher for his attempt to jump McGregor's Gorge of Doom with his motorcycle during his days as "The Flying Fishmonger". The theme song and its updated version are heard during the Phineas and Ferb episode "The Flying Fishmonger" and are revealed to be integral to the plot of the episode.

Lyrics
(First Version, sung in a monotone and Scottish accent)

He's a fishmonger and he flies

He's a fishmonger and he flies

(Second Version)

(Choir) Holy, Holy Mackerel

Holy, Holy Mackerel

Holy, Holy Mackerel

Holy, Holy Mackerel

Phineas Flynn: He's bald on top

He's got an artificial hip

He's gonna take a hop

He's gonna take a trip

He's weak in the knees

And he can't find his keys

But put your hands together

'Cause he's here to please

He's a Flying Fishmonger (Flying Fishmonger)

He's a Flying Fishmonger (Death-Defying wonder)

He's a Flying Fishmonger with nerves of steel

He's got an old blender motor

And a pair of wheels
