These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fountain of Memes: Pretty much everyone in Generation Y knows his stand-up routines by heart.
"Funny Aneurysm" Moment: Following Mitch’s death, most of his drug-related humor became this. Also, his posthumous album, Do You Believe in Gosh? contained several jokes that he was still ironing out all the kinks to, prompting him to comment on how this joke wasn’t ready yet and that joke will be fixed in the future, etc.
Hilarious in Hindsight: On his first CD, he makes a lot of jokes about how the audience's laughter will be edited onto every joke, to make it look like they are laughing all the time. While that doesn't seem to be the case on the album (there are several jokes that fall flat), this is exactly what Comedy Central did for his special. Watching the unedited version reveals that his regular 30 minutes mostly fell flat, so he stayed for another 20 and delivered some older material, which the audience responded to much better, and the network mixed the two together.
