They also have a history of joke collections and quote from the most ancient surviving joke collection, "The Philogies." It seems jokes have progressed very little since the 4th century. Here is one about a classic Greek stereotype called the "scholastikos" or, as the article states the "absent-minded professor" or "egghead."
"An Egghead was out on a sea voyage when a big storm blew up, causing his slaves to weep in terror. "Don't cry," he consoled them, "I have freed you all in my will.""

There's a few hacky, obvious sketches on a few episodes. Keep in mind, the ratio is very small, but they're there. I won't name them, 'cuz they were written by friends, all of whom write brilliant shit 99% of the time. The ratio of hacky shit that sneaks onto MR. SHOW is the EXACT SAME RATIO of brilliant shit that sneaks onto MAD TV. It's like a Bizarro Universe version of MR. SHOW. Where Bob and David have a Shit Detector that's sometimes on the fritz, MAD TV has a Quality Detector that, for some reason, fails to power up, and something really brilliant gets through."
