There's this one time that really sticks out for me.
I'm at my best friend's apartment in the city. Well, it's not his apartment, it's his grandmother's apartment, who has migrated to Florida for the winter. It's him, me, and my other best friend. I've decided to stay over and just go to work from there in the morning.
We're hanging out, doing nothing in particular. My buddy has a porno lying around and puts it in. It's on in the background, on mute, while we're talking. (this sounds fairly homoerotic but I can assure you it isn't.)
Anyway, my mother calls me on my cell phone. So I start talking to her. My buddy goes to the television and blasts the volume. So I'm trying to talk to my mother, and all that's being heard is "Oh! OH! OH! PUT IT IN MY ASS! PUT IT IN MY ASS!!!!"
I want to be pissed at him, but I'm laughing so fucking hard that it's hurting me, and I'm crying. I frantically run to the television, but it's one of those really old televisions where the knobs are all fucked up, and in my state, I can't figure out how to turn down the volume, or turn the television off.
All the while, my mother is on the phone, getting angrier and angrier, going, "Hello? What's going on? Who's over there?" I can't even respond to her because I'm laughing so fucking hard. She winds up hanging up on me. I called her back about 10 minutes later when I had finally regained composure...from a different room, of course.
The next day, I had a cough from laughing so hard. It was unbelievably funny to us.
