We recently polled readers on which booty-loving song was best, and well, this time we're going a little further south. Two of our favorite celeb hunks (that would be Justin Timberlake and Channing Tatum, of course) have provided fans with laugh-outloud songs about, uh, their junk. Justin Timberlake gave us 'D--- in a Box,' and Channing Tatum delivered 'The D--- Graze.' Whose song is best?

When Justin Timberlake joined The Lonely Island to perform 'D--- in a Box' on 'SNL,' our lives would never be the same. The song is hysterically raunchy, but sung so seriously that we can't help but pee our pants laughing. But in addition to the hilarity factor, the tune is actually a pretty addictive slow jam -- and Timerlake's falsetto vocals sound flawless.

Channing Tatum's 'The D--- Graze' is the comedic jam we never knew we needed. The video not only features Tatum rapping (yes, please) but he's also spitting hilarious rhymes and demonstrating how to do his favorite kind of, shall we say, "alternative handshake." What could be better?
