Can someone help me with a quote?

what episode when Chris says:

"I'm going to turn you into poo"

Trick question? None of them. I believe the quote actually is, "Ha ha, I'm turning you into poo." It's found in "He's too Sexy for his Fat", when Chris is concerned about being overweight and Peter ends up getting liposuction. To help Chris exercise, Peter hangs a twinkie off the end of a rod attached to Chris's head so he'll run around chasing it. Chris finally learns all he has to do is lie back on the ground and the twinkie falls within reach, allowing him his triumphant gloat...erm...of turning it into poo. (Surely there *can't* be another quote quite so similar?)
