Shane's practicing guitar in the living room when those skanks he hangs out and has threesomes with come in, without knocking, and immediately start jabbering at him. He's like, "Hi?" The mean one beats around the bush, and finally the dumb one goes, "It hurts when we pee." Cut to him standing there holding a flashlight while they investigate his penis and say things like, "Nothing on the underside!" until Andy opens the door. His first response is to back out of there with a quickness and feel gawky and tell them to have fun, but his second more mature response is to come back and be responsible.
Shane says they might have something -- "Not tonsillitis," Andy guesses -- and when one of the skanks says Chlamydia, Andy tells them to go home immediately and discuss it with their parents like in She's Too Young, and not have any sexual encounters on the way home. Heh. Shane protests, once alone with Uncle Andy, that it's nothing, and Andy's like, "Oh, it's something. Until we make sure it's nothing." Then, Andy's Sexual Adventures Part 1,647: Boy Have I Had Some Sexually Transmitted Diseases In My Time, which is what you call a character tic.
Celia: "Take a deep breath... Hold that breath... And let it out." Get it? Like a yoga instructor, but for pot! The simultaneous exhalations of her mall-working pot club cause the smoke alarm to go off, so Danielle -- the pink-on-pink chick who hit on Isabel before -- knocks it down with a well-tossed shoe or something, because she's on the softball team, because of course she is, because she's a lesbian. Get it? Again? That scary Edie Britt Orange You Thirsty lady that wouldn't quit it last week is back, asking too many questions so that Celia can give us the whole setup: they buy the "beauty products" on their credit cards, and since the pot club closed down they sell more "beauty products" to their friends, also on credit cards.
