Zii!! (wearing the right pin) and Gary!!
And dun dun dunnnn for 'Sabrina' and her school outfit... oh my... could it be?... The fact that Andy and Mulligan are not quite paying attention is nerve wrecking!
I like how Peter shoots down Andy's forceful return from last page.
I agree with Sal Monella, Guest, H0lyhandgrenade, darkamnios, cals and Maritza Campos (yay, another fellow webcomic author commenting on your comic, Mr. Twist!), "Sabrina" is ... her.
But I disagree with RadicalTrain, this isn't going to be fan service. I mean, Michelle's been doing stripping her top off, having sex, grabbing her boobs, having her nipples show through a jumper (not necessaryily in that order), just about everything everything this side of full frontal nudity, which this comic doesn't do anyway (what are you all looking at me for? Of course this comic doesn't do full frontal female nudity). So I don't expect anything we haven't seen yet (yes, Mr. Twist, you may take this as a challenge).
dangerface: I wondered about that myself. Evidently it's someone with such a cool shirt that it had to be cut in order not to attract too much attention supposedly focused elsewhere.
(Speaking of that last panel, the orange-shirted guy with the cap seems to have closed ranks with the bearded stud quite quickly after being practically on the other side of the stage one panel earlier. Zii, Gary and said stud must have closed ranks too since now it's Gary who is between Andy and the stage and not the stud as in the penultimate panel.)
Jodie: first, a stripper whose number revolves around jailbait could very well style herself as Sabrina the Teenage Witch.
However, note that this was in the mid-to-late nineties (after Seven came out, before Star Wars Special Edition), so Sabrina the Teenage Witch may be a little new to Michelle (assuming she doesn't read comics). It could also be a reference to the comic, but then that's a bit old for someone who was born in the mid-to-late seventies.
It could also be a reference to the European singer, or one of the movies (the remake with Julia Ormond came out in '95, like Seven). Of course, if one person looks exactly unlike Michelle that'd be Audrey Hepburn, but there you go.
(But then, now that I've expounded my wikipedia culture, I just think that a stripper disguised as
