That Sinking Feeling (Phineas and Ferb)

Baljeet wants to impress his childhood friend from India, Mishti, so he enlists Phineas and Ferb to help woo her. However, none of their over-the-top romantic gestures impress her, as she likes Baljeet for who he really is. Meanwhile, Perry must stop the sleep deprived Dr. Heinz Doofenshmirtz from moving the Danville Lighthouse to the other side of town so that he isn't bothered by all the ships.
