Lyrics
If you're happy and you know it, poop your pants!
[fart noises]
PBBT!
PBBT!
Repeat If you're happy and you know it, poop your pants!
[repeat fart noises]
PBBT!
PBBT!
If you're happy and you know it than your underwear will show it
If you're happy and you know it...
[The end, but then got cut short due to Petey yelling]
