Several years at my job I went to the bathroom. In the stall next to me some guy comes walking in, and well I guess the person prior to using it left the seat up and he also wasn't paying attention, because then I heard a big splash followed by a copious amount of swear words. I was dying. Dude...clearly wasn't paying attention when he sat down to do his business. That's easily one of the hardest things I've ever laughed at. I wasn't just cracking up. I was full on laughing out loud.
As I finished and was washing my hands I was still laughing and then I hear from his stall...."yeah....I'd laugh too."
Back sitting at my desk a few minutes later I'm still laughing. I'm laughing now just thinking about it.
