He is that dense.

Gary: Where were you last night?
Mac: fighting crime
Mac: I mean
Mac: eh fuck it
Mac: i'm a superhero
Gary: haha
Gary: Definitely needed your commentary last night.
Gary: I got stuck as some kind of bizzarro third wheel
Mac: who was there?
Gary: Wes and I with Angie (girl Wes is trying to bang) and her lesbian friend.
Mac: good thing I wasn't there
Mac: I would probably ruin things inadvertantly on account of being bored
Gary: That is all I wanted.
Gary: At least is would have been less awkward at times.
Mac: well you gotta mention that next time you say you want to hang out
Gary: Haha, I didn't know this was going to happen.
Gary: Ah, whatev...
Mac: haha you should've asked the lesbian
Mac: "are you really a lesbian are you just trying to avoid me hitting on you"
Gary: Oh, so much I would have said if Wes wasn't trying to mack it.
Gary: I tried to be good, but I know if you were there you wouldn't feel as obliged.
Mac: haha and how
Mac: but if you want to actually hit a party come with me friday to a barbeque in new haven
Gary: Friday?
Mac: yup
Gary: Hmmmm......
Gary: I'll see.
Gary: May actually skip Battlestar.
Mac: priorities man
Mac: when's the last time you've been "out"
Mac: you know of the closet.
Gary: Not in a while.
Mac: ZING!
Gary: O, a LOOOOONG time
Gary: haha
Gary: I may actually have a girl to bring along.
Gary: I'll have to see.
Mac: oooo
Mac: look at you
Mac: not being gay
Gary: I'm so proud of myself.
Mac: where did you meet her?
Gary: At the gym.
Mac: nice
Gary: Yeah, I haven't been talking to her too much yet, but this may be an oppurtunity.
Mac: do it now
Mac: don't invite her last fucking minute
Mac: she's not one of your friends, she'll probably actually have plans for a friday night that’s not "Battlestar"
Gary: I won't see her again until Thursday.
Gary: Haha, well she works on Fridays and gets off later, so I'll see.
Mac: you fuck… you didn't even get her number yet?
Gary: I work slowly, VERY SLOWLY.
Mac: well here's your fucking chance
Mac: though it's extra slim
Mac: since your throwing this on her last minute
Gary: I will see what's happening.
Gary: If I knew yesterday I could have asked her then.
Mac: you should've mention it
Mac: i wouldn't have cared but I might've remembered a social event you could bring her too
Mac: or fuck it, if you really like the girl
Mac: MAKE AN EVENT
Gary: I may be able to see her this Tuesday. That would be ideal.
Gary: And I will make an event.
Mac: if you’re thinking battlestar or videogames you are an idiot
Gary: You don't think she'll like battlestar. Mark and Liz are nice folks.
Mac: hmm
Mac: no your right
Mac: who doesn't love battlestar
Gary: I knew you'd see it my way.
Mac: alright i gotta go for a run
Mac: think "bar grill"
Mac: think "down town"
Gary: Alright.
Mac: think "what to do normal people do"
Gary: I'm not that dense.
