Looking for a stupid, fun to read book/series while I wait for Song of Ice and Fire.

So, I just ordered the paperback set of "A Song of Ice and Fire" and it might take a week+ for them to get to me, and I've got this itch that needs scratching while I wait, just something stupid and funny while I wait, fantasy or sci-fi (although I might favor sci-fi because I haven't read any for a long time). I'll consider every recommendation, and thanks!
