TGIF! This 'Tonight Show' theme song is so '90s fabulous

Remember when you just busted it for five whole days at school, and those four, beautiful little letters — TGIF — meant that you were free to unwind in front of the TV for, like, two hours?

Are montages of shows like Boy Meets World, Family Matters, and Step By Step running through your head? Good! Then you're ready for The Tonight Show's TGIF theme song.

The home featured looks straight out of Full House, and we think Questlove might've rummaged through Joey Gladstone's closet to find that shirt. But the authenticity of this parody doesn't stop with the fashion. We've even got two guys, Colin and Tyler Foley, to play the part of James — whoever he is!

Let's not forget the lyrics that are written in classic TGIF sitcom style.

"When the night has fallen, and the day is done, your soul is aching for that special someone. The world's gone crazy, caught up in concern, but a smile's awaiting. You know where to turn."

Thanks, Jimmy for making us feel like kids again!
