One of my fav song off of Opposite of December is Nerdy.

Weird Al's parody of Chamillionaire's "Ridin' Dirty". From the album Straight Outta Lynwood released on Sept. 26, 2006. Anthem to D&D fans, anyone who speaks klingon, and nerdy white kids creating entries on websites such as this one. Also arguably more entertaining than the original song.
"I’m nerdy in the extreme
And whiter than sour cream"

"They see me roll on
My Segway
I know in my heart they think I’m white and nerdy"

A song more entertaining and smarter then the original. Sung by ''Weird Al'' Yankovic, it features many stereotypical ''White and Nerdy'' things -non-spinning tyres, Wikipedia entries, Chess Club, Mayonnaise, Action Figures and braces instead of grillz....hilarious!
White and Nerdy is a really funny song, one of his best!
