what i liked- Eric's "I'm never peeing again!", Jack asking for a sandwich and then Eric asking Rachel for one also, Cory singing along with Morgan, only him singing to his dad, the 'celery' poster on his wall, Shawn's "I called my dad average. He was thrilled."
Good episode. It had some great humor and a good plot. I never was a fan of this one, but upon rewatching it, it is a pretty decent episode, i think so anyway.
