Years back, two guys that I used to work with, who coincidentally are now both deceased, were having a conversation about their vasectomies. Didn't think anything of it until a couple days later the one guy's wife, who was a bar tender at a local dive bar, stops by with their kid who happened to be an infant. The wife leaves and then math kicks in. So, I ask the guy about it and he goes into this long winded story about how "the vasectomy failed..." Probably one of the hardest things I ever did was keeping a straight face as the two guys standing behind him burst into silent laughter. One of them, who basically resembled a small grizzly bear, turned around and put his face into his locker and did that thing where your whole body spasms while the other covered his mouth with his hand as his face was turned three shades of red and tears streamed down his face as he exited stage right.
