I laughed out loud in Church one time. Some dude was kneeling and praying and when he stood up, he cracked his head hard as fuck on the Holy water thing that's attached to the wall. Water spilled all over his back n shit. haha
I usually do laugh inside my head, but sometimes gotta play it off if I slip, bust a lil cough or something to disguise the laugh. If some dude talks fucken stupid, has a deformity of some sort, blinks a lot, has a fucked up haircut, I don't give a fuck, I'm laughing, either silently in my head or I have to play it off. I'm not one to easily let shit slide by, I'll notice it. I'm too observant.
