Elvis: I was dreamin'. Dreamin' my dick was out and I was checkin' to see if that infected bump on the head of it had filled with pus again. If it had, I was gonna name it after my ex-wife 'cilla and bust it by jackin' off. Or I'd like to think that's what I'd do. Dreams let you think like that. Truth was (pause) Elvis: I hadn't had a hard-on in years.
