Not really that funny

I remember watching this as a 16yr old with a bunch of friends and about 20min into it we all wanted to turn it off. But we watched it all, although it never really got better. I watched it again as an adult and it didn't get any better. It's just not that good. It's him coming back on stage and basically winging it. He obviously hasn't been in front of an audience in awhile but that's not it. It's not like it would have been better if he wasn't so nervous or rusty. It's just not that funny.
