Boy ... meets world.

There's absolutely no reason why this particular 'Tonight Show' skit should exist or why it should work so well or why it should be so instantly enjoyable and quotable, but alas, it is all of those things, and so much more. 

On last night's show, host Jimmy Fallon introduced, with little fanfare, international superstar slam poet (go with it) Samuel L. Jackson, hitting the stage with a brand new jam -- an ode to 'Boy Meets World.' It is, without qualification, an instant classic. Just enjoy it -- and be ready to have the dulcet tones of Jackson and his smooth jams stick in your head all day.

Topanga, Topanga, Topanga.
