And I like Raj! I hope they give him a love interest soon.
I mostly have a problem with the single-shaded nature of his character. His shtick was funny the first time, but the whole not being able to talk to girls throughout a significant amount of the show gets very boring after awhile. The whole drunk thing not-withstanding. I just want them to flesh out the character a bit more.

Howard is a pretty annoying character too but for the same reason as Raj.
