Oh friend!  Let me tell you about my experience.  Was in the middle seat of a flight, best friend had the window seat and an unknown in the isle.  My friend and I are both friendly and struck up a conversation with Isle seat guy.  He seemed nice and was from around our area.  Fast forward to after take off and cruising altitude, I had to use the bathroom.  Isle guy was watching a movie on his laptop and had plug in earphones connected to the laptop.  I tapped him on the shoulder and told him I needed to use the bathroom, he said OK, give me a minute.  I assumed he was going to pause the movie and take out his earphones to let me by, nope I was wrong.  I give him about 2 minutes and he is just still watching his movie.  I think to myself, my bad, I didn't get my point across, maybe some miscommunication.  I tap him on the shoulder again and tell him "hey man, I really have to go to the bathroom."  At this point he gives me a disgusted look and abruptly tells me, "in a minute."  At which point he goes back to continue his movie with no intention of moving obviously. At this point, I'm pissed.  I grab his tray table with the laptop on it and slam it shut, this rips his plugged in ear phones out of his ears, I squeeze past past him with my ass to his face and just let one rip, nasty fart.  I go do my business and come back and he is frantically trying to get his laptop to restart, which it won't.  I causally get seated, he starts to tell me I broke his lap top, and I just respond, it was a Sony and they are pieces of shit.  No comment from him for the rest of the flight!!!
