Jimmy Fallon and The Backstreet Boys Unite!

Jimmy Fallon always seems to do the craziest things I could only dream about to do with celebrities. From locking them in phone booths, sing with them in a subway, and even this bit where he takes a group and gives them and Fallon's house band classroom instruments to play the groups hit song on.

I almost dropped my phone when i saw Fallon, in all white, sitting down with THE Backstreet Boys to sing "I Want it That Way". I sang along the entire time (especially ALL of AJ's parts, he's my favorite).

For those of you that get confused, BSB is the group that doesn't have Justin Timberlake (therefore NOT as good as NSync!)
