Taj Mahal Badalandabad (played by Kal Penn) had a few funny moments in the movie (i.e. jokes regarding the former British aristocracy in India), but the movie almost nothing but sex jokes for the entire movie. This sort of humor included nearly a dozen different euphemisms for the female anatomy (I lost count), and countless jokes about how to "score" with the opposite gender. I laughed at the first few sex jokes, but by the end of the movie, I was really tired of hearing crude jokes.
If this sort of humor is appealing to you, then you'll enjoy this movie. Otherwise, don't bother seeing it. Overall, I felt "Harold and Kumar" was much more humorous. I'm a fan of Kal Penn's, but unfortunately, I cannot recommend this movie.
Brief Plot Synopsis (no spoilers below): Taj heads to Camford University (name taken from Cambridge and Oxford) in England to pursue his higher education and to follow in his fathers footsteps. He believes that he has been accepted to the prestigious fraternal guild "Fox and Hounds". However, upon arriving at the University, he is told by a "Fox and Hounds" member (nicknamed "Pip") that he was mistakenly sent this acceptance letter.
Taj is forced to become a teacher's assistant at the "Barn" residence, which contains a group of social outcasts. Pip and the other "Fox and Hounds" members treat Taj and his house mates very poorly. Determined to help the members of the Barn residence gain acceptance, Taj starts the "Cock and Bulls" fraternal guild. He hopes that the "Cock and Bulls" guild will win the Camford Cup, which is an annual academic, social, and athletic competition between fraternities. The bitterness between Taj and Pip only increases as the fraternities compete in several competitions to earn points towards the Camford Cup.
I cannot say anything more about the plot, or else I'll spoil it for you.
