Lip drags Ian to Karen's house for a last-ditch blowjob; her mom Sheila acts crazy some more and it's just like going home: "Karen! Honey, your little helper is here!" Can't you just hear Joan Cusack saying that? Inside, she offers them "homemade lime-chicken chimichangas," and when Karen's dad comes in, he looks around for his daughter. Lip tells him she ran upstairs to check Google Earth and see where Isaac Newton was born (!).
Sheila tries desperately to get a kiss from her husband, telling him to guess what she made for his lunch. Somehow, it's all very depressing. Like one of those Lean Cuisine ads where the ladies are so happy about their lunch. Also, I didn't mention this earlier, but their house is clown central, which makes all of it -- the weirdly permissive mom, the blowjobs, the crazy cooking, the mean dad -- about ten times more surreal. Cookie jars and piggy banks, some holding balloons and some bare-handed. It is grooooss.
Karen's dad guesses first "Cornish game hen with Asian pear," and then "wild salmon with baby carrots," but when his wife asks him for a kiss to tell, he snarls that he'll find out when he opens the damn bag. Sheila is totally out of it and totally trapped, like if you crossed Betty Draper with Annette Bening in American Beauty and then gave that person an acceptably dotty, sweet personality -- perhaps Joan Cusack's personality.
This whole time the gay one is getting a blowjob from Lip's tutee, right, so eventually something knocks an apple off the counter and it rolls over to the other side of the table and as shitty dad's on his way out, he bends down to pick it up and sees his daughter crouched with her face in Ian's crotch and she leans back and nearly smiles at him, not in a creepy way but like in a nearly pretending nothing is happening way, but wiping her mouth, and then things get really fast and scary and the boys are running around the house and jumping out of windows trying to get away -- and poor fucking Sheila is completely bizarre, screaming, "It's only a study group!" and that -- and finally the dad's out on the sidewalk in front, yelling "The farther you run, the more I will kill you!"
