Bless You, Will Smith, for Doing the 'Fresh Prince' Rap on 'Ellen'

"This is how we know if we got real fans in the house."

It's all downhill from here, people—this is the best thing you're going to see today. While visiting Ellen, Will Smith decided to delight the audience (and give us some serious '90s nostalgia) by rapping the Fresh Prince of Bel-Air theme song. 

"This is how we know if we got real fans in the house," he said as he stood and launched into the theme song. Fun fact: The show premiered in 1990, and Smith has apparently figured out how to stop time and the aging process, because dude looks good

Watch the awesome moment below—there's a cute little call-and-response thing happening:
