Crashdown. Liz stage-directs some cleanliness onto a milkshake machine. I really hope the regular patrons of that diner like themselves some soap-and-dishrag-flavored shakes, because that's the only thing Liz is ever cleaning when she's allegedly doing any work in there. Maria "I'm Gonna Wash That Man Right Outta My Hair" DeLuca assures Liz that everything will be "okay," and their vamp is soon interrupted by Michael "I'm Gonna Never Do Anything Remotely Resembling Washing My Hair, Thanks" Guerin, who rings the short-order bell as an introduction to plot-developing, "So when does Billy get here?" Liz interjects an ill-timed pause so drearily long that the remaining six of us exchange a brief hopeful glance and one of us even mouths the words, "Did they just cancel this show in the middle of an episode?" before finally -- FINALLY -- getting around to responding, "Billy who?" Billy Darden is how the closed-captioning spells it, and Liz elucidates that "First-Kiss Billy" is coming to Roswell. From the next stool over, a suddenly-appearing Kyle -- fresh from piling enough copies of the New Mexico yellow pages onto his chair so that he could see above the counter and sneak unsuspecting into the frame, notes, "Your ex-boyfriend is coming to visit? That's not legal." Chatter chatter about how he wasn't her boyfriend, that they kissed once when they were thirteen, and we discern that First-Kiss Billy (or, as the deep, artistic philosopher would probably prefer to be called, "FK Billy") will be staying at Maria's house while her mother is out of town. Kyle finds this arrangement unacceptable, climbing down from his stool and walking over to the counter, explaining, "Michael, Michael…" Did anyone else tack on a totally dumb and Rocky Horror-esque "Motorcycle!" at this point in Kyle's speech? You're so not alone. Kyle explains, "Here on planet Earth we have this thing called jealousy." Michael responds that he has nothing to be jealous about, and that "they were thirteen-year-old geeks at band camp." Awwww. Making fun of band camp. How quaintly 1999 and pre-war of you "writers." Maria hilariously carries Kyle back to his stool by the collar like a mother cat carries her tiny, tiny young (the cats don't have the unenviable task of completing this activity while their young pretend to be five inches taller in orthopedic shoes, which is probably what renders this gag here so "ih"). And then, there's Billy. And he's totally not a band camp geek anymore, because he carries a guitar case rather than a tuba or lute case, and Maria doesn't even recognize him all these years hence. He looks Maria right in the eyes and announces, "It's me," leaving off the additional, "Wacky cameo actor Jack Black," because the six of us who still watch this show obviously lack any kind of crap filter and we're probably the exact same six who ponied up the cash to see Shallow Hal, now aren't we? I know, it's not really Jack Black. But he's the damn "Land-of-Confusion"-video cloth-and-buttons spitting image, now isn't he? He hugs Maria and Michael looks away, a dozens eggs spontaneously bursting in their carton for as-yet-unknown reasons. Maria suggests to Hal, "Let's go this way." This way is out. They want to be alone. Meanwhile, Kyle Gass sits forlornly in the parking lot, all, "I'm way too Garfunkel to go solo now."
