Only "live" tv show I've seen was Aqua Teen Hunger Force and it was hysterical. I'm going to go see Whitest Kids U Kno at State too. I figure, why not? If it sucks then that sucks, but if it's funny and worth it then it's win win. I figure if I like the show and the comedians, it's worth a shot. I remember seeing Fred Armisen on Premium Blend on Comedy Central and thought his stand up was hilarious, but it was skit related. Like it wasn't jokes as much as it was skits. One of the skits he used to do in his stand-up routine actually turned into an SNL skit. It was some sort of self defense class, pretty funny.
I like Portlandia, 35$ is kinda steep, but I think it'll be fun.
