Warning: You will want to rock right now.

Will Smith stopped by “The Tonight Show” on Thursday and joined Jimmy Fallon for a beat box version of “It Takes Two.” The two used an iPad app all Billy Joel-style to make looping beat boxing tracks and then put their own spin on the rap.

Earlier in the week, Fallon also did his own take on Smith’s “Fresh Prince of Bel-Air” title sequence, pretty much matching it shot for shot. So between that and this new video, you can probably say, “Smell ya later,” to the rest of your day.

“The Tonight Show Starring Jimmy Fallon” airs weeknights at 11:35 p.m. ET on NBC.
