From the episode "Into Harmony's Way" (season 12). I can't poop in strange places (Strange places) I can only poop in my home It's as though I'm watched by strange faces (Strange faces) It's why I never roam I've left Stewie alone with strangers (Strangers...) To satisfy my fecal needs... I've put my whole family in danger To poop before my anus bleeds Home bowl, home bowl You know just what I need Home bowl, home bowl Poop before my anus bleeds
