The 40 Year Old Virgin
Honestly, I even think that this movie could have been either more disgusting (as in the American Pie style of sexual humor) or more romantic (as in the Maid In Manhattan style of chick-ness). I don't necessarily think that it worked to turn it into a romantic comedy at the end, but the movie still had its great, sex comedy cliches everywhere. I would not have expected anything less, so it's great to see that they followed through on some.
I would definitely recommend this movie; it's easily worth the price of admission.
