arjunrajlab shares a surprisingly good joke from the Fable model:

> Why do mathematicians mix up Halloween and Christmas? Because Oct 31 = Dec 25.

The punchline is a base-conversion pun: 31 in octal equals 25 in decimal (Oct = octal, Dec = decimal). The author says he only unearthed this gem after probing a bit further and calls Fable's answer unexpectedly delightful.
