'Jimmy Kimmel Live': Manny Pacquiao sings yet again

It's become somewhat of a tradition for Manny Pacquiao to visit "Jimmy Kimmel Live" on his November trips to Los Angeles during breaks from his duties as a congressman in the Philippines. And part of that tradition, of course, is for the world champion boxer to break into song.

Last time he was on the show, Pacquiao did a duet with actor Will Ferrell. Their version of John Lennon's "Imagine" got over 1.5 million hits on YouTube.

This year is no different -- Pacquiao stopped by Kimmel's show this week, a good luck charm before his upcoming Nov. 12 pay-per-view fight against Mexico's Juan Manuel Marquez. This time, he dueted with Jimmy himself. The two sang "How Deep Is Your Love" back-to--back.
