Family Guy/South Park/American Dad/Simpsons
American Idol and shows like it.
Reality shows.
Anything to do with celebrity gossip.
Kim Kardashian.
Rebecca Black and every other Youtube "celebrity" that exists forever.
Jay Leno, David Letterman and Jimmy Kimmel.
Basketball.
The Vampire Dairies, Twilight, and almost anything vampire-related. This includes, to a lesser degree, True Blood. It is a decent show, the best of the vampire shows, but it isn't amazing or incredible in any way.
Dane Cook.

I could continue going probably.
