Once went to play poker with my mate and his brother, and a bunch of his brother’s mates I didn’t know. We were chatting as you do, and got on to the topic of what you’d do if you won the lottery. One of the lads said, totally serious, “Oh, I’d buy a suit of armour”, as though that were the most natural first decision anyone would make. Everyone cracked up, and then whenever the dude tried to speak for the rest of the night, everyone would make “clunk, clang” noises over the top.
Probably doesn’t sound very funny, but trust me, you had to be there.
