S.I.M.P. (Squirrels In My Pants)

S.I.M.P (Squirrels In My Pants) [From 'Phineas And Ferb']
There are squirrels in my pants!

Tell me what's makin' you jump like that
S-I-M-P, squirrels in my pants
Ain't got no chickens, ain't got no rats
S-I-M-P, squirrels in my pants!
S to the I to the M to the P
Then maybe you can be moving like me
Step right over and watch me put it down...
Squirrels, squirrels (S to the I to the M to the P)
Step right over and watch me put it
S to the I to M to the P
