JoeBob was down on his luck after a series of unfortunate events, and started going to a local bar every night. There was a group he noticed in one corner that were always there but they did the strangest thing. Every once in a while, one of them would go "27" or "14!" or "112" and they'd all laugh and laugh. Finally after a few nights, JoeBob asked one of them why the numbers were so funny. "Welp" one of them started. "We've all been coming here so long, telling all the same jokes, we finally just made a list. Saves time to just remind ourselves of the good ones instead of going through them all again." After a few weeks JoeBob had starting sitting with the group and one night, after a couple of beers, he goes "37!" and there was utter silence. One of the regulars looks at another and goes "Welp. Some folks can tell 'em, some can't."
