At this time of year, terrible and/or groan-worthy jokes come to the fore, and are completely acceptable, and in some cases encouraged, provided they’re preceded by a bang noise and read out from a tiny piece of paper.
Rummaging around on my computer today, I found a set of mathematical Christmas cracker jokes I wrote for a party thrown for a group of mathematicians a couple of years ago, where I hacked apart a set of crackers and replaced the toys with tiny slide rules, the paper hats with ones cut into fractal curves along the top, and the existing awful jokes with awful mathematical ones. I thought I’d share them with you all, since they’re more likely to be appreciated by maths fans.
