If you didn't find Norm funny, you're prob not familiar with his comedy
All the people who hated Norm's set, most likely aren't familiar with Norm's sense of humor and personality. Norm has always been known for being a dick and not giving a crap about what people think and always does jokes that test the audiences patience. That's just Norm, he doesn't give a crap.
Most the complainers are probably in high school or younger and weren't old enough to watch late night tv in the mid-late 90s when Norm *beep* KILLED on SNL every week. Any fan of Norm's "SNL Weekend Updates" or his numberous Conan/Letterman/Stern/Dennis Miller Live/etc appearances would definitely appreciate what Norm did tonight. All the haters are probably a bunch of high school dorkfags who probably only know Norm from the time he appeared on lame-ass Family Guy.
