For no reason...
I decided to come here and post 2 of my favorite subtle "adult" CG jokes. (One is "adult" in the "sexual" sense, the other in the topic it conjures):
1. When Karen is giving Brent a haircut and Emma walks in, asking what's going on. Brent says "I'm getting a little trim from Karen.... I mean Karen's cutting my hair.
2. After getting himself involved with the knitting club, Hank comes into the Ruby and sees several members there. He greets them with "Hey hey hey! What's up', my knitters?"
