Major Boobage was a good one. Made a good joke out of Heavy Metal, pointing out how overrated it was due to that it had boobs in it. Also, I one time the caption option on my tv managed to show what Kenny was saying during the episode whenever he talked, and I laughed.
Fishsticks was great in how they made fun of Kayne West and his gigantic ego. It was also funny of Comedy Central to play that particular episode six times back to back shortly after Kayne's actions at the MTV Music video awards.
Dances with Smurfs did a great job in showing how much a jerk Glenn Beck is, in how Cartman parodied him and how it's dumb of people to actually listen to people like that. And although it was funny for a short time with the "Dances with Smurfs" joke when it satirized Avatar, it did get old quick since too many people ran the joke to the ground.
Butter's Bottom B*tch was also funny. Hearing Butters talk like a pimp was hilarious.
Last but not least, Dead Celebrities was good too. Mainly for near the end when Michael Jackson leaves Ike's body, and once Ike is back in control of himself, he started cursing as soon as he realized what he was wearing. Never expected him to talk like that.
