Flying 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 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
