<human>: So we're at lunch right, and everything's going great, then my pal (calling him Dave) decides it would be funny to eat a banana while making I contact with someone else. So I tap on some random guy's shoulder and he turns around. Dave then proceeds to give the banana a bj .

Then it occurs to me the guy he's doing it to is gay. And Dave doesn't know.

So at this point I've realized that, and I just lose it. Dave thinks it's due to his antics so he begins to step it up a couple notches. Rubbing his nipples and moaning. The gay guy is halfway between bemused and amused at this point. I'm literally on the ground gasping for air.

Then Dave deepthroats the banana. Then it breaks. In his throat.

See it broke in such a way that he couldn't cough or pull it back out, and too big to swallow. So Dave is literally choking, but I didn't know that. In between my bouts of laughter, I look up, see him choking, and laugh even harder. I'm thinking, man he's really into this. He even made himself get red in the face and everything. He gestures to me frantically, and again I keep laughing thinking it was all part of the act.

Then the gay guy got up and gave him the Heimlich maneuver. Then Dave to was gasping for air. He owes him his life now.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Friend chocked on a banana while trying to be funny; I almost let him die because I thought it was all an act.
