Clark goes to Lex's pad and finds Lex doing some sort of business on the phone. Lex giggles with delight when he discovers Clark totally eavesdropping. Lex continues the double entendre-ville when he says that he's sure Lana told Clark about Lex's "nocturnal adventure." Who doesn't hear "nocturnal" and think that the next word should be "emission"? Clark asks Lex if he's okay. Lex says he hasn't lost his mind, and that he was just sleepwalking. Clark says that Lex could have killed himself, and Lex says that when he found Clark asleep in the road last year, he didn't question Clark's mental health. Clark has no comeback to that, so Lex smirks and walks away. Clark turns and says that he's not the one who just got out of the loony bin. Lex says that his doctors think he's cured, so why doesn't Clark? Lex walks out, and Clark stifles a belch. That's what it looked like to me.
