Surreal Video Of Will Ferrell And Manny Pacquiao Singing John Lennon's "Imagine"

Many of you have seen it by now, but maybe some of you haven't. Here's Will Ferrell's duet with pound-for-pound king Manny Pacquiao, singing the John Lennon classic "Imagine" on the Jimmy Kimmel Show last night.

Sometimes, it's fun to think of what the world would be like to you if you were suddenly transported 10 or five years into the future. Can you "imagine" (tee-hee) what the you of five years ago would think of this video today?
