Yeah his stand up is pretty poor tbh. He doesn't even have a great sense of humour. He had Maccauley Culkin on a few years ago and 90% of Culkin's jokes went over Joe's head.
The thing I'm most grateful for Rogan is probably introducing me to Bill Burr though. His stand up is incredible. Conversely, Burr's podcast is painfully poor weirdly enough.
Favourite/most infuriating Rogan moment has to be him not only failing to understand the Infinite Monkey Theory, but actually attempting to argue with Brian Cox about it.
