Now that I don't feel sick to my stomach I am finally getting well Give me one good reason to give it another try That's what I thought, that's what I thought Now you're asking me to come back 'round again Just as soon as I left town Can you tell me how it's any different That's what I thought, that's what I thought I'm not a pig, one that goes back again to roll 'round in the mud I know better than that I'm not a dog, I'm not a dog returning to its vomit I know better than that I hear the doorbell, it's the snake oil man And I'm not feeling too polite I turn the porch light off while I look him in the eye Sir, not tonight, no, not tonight I'm not a pig, one that goes back again to roll 'round in the mud I know better than that I'm not a dog, I'm not a dog returning to its vomit I know better than that I know better, better than that Now I know better than that I've learned my lesson, I have learned my lesson I'm not going back, I'm not going back I'm not a pig, one that goes back again to roll 'round in the mud I know better than that I'm not a dog, I'm not a dog returning to its vomit I know better than that It might have worked back when I was young and dumb and desperate But now I'm old and wise and mad I've learned my lesson and I don't have to be like that anymore Cause I've learned better than that Hey, I know better than that I know better than that
