Thank goodness for iPad apps. On last night's ‘Tonight Show,’ host Jimmy Fallon—who grows more California by the minute, as the show has temporarily relocated to the West Coast—and guest Will Smith decided to finally give the people what they want: rapping. Well, sort of.

Using some sort of magical iPad app (they are all magical, right?), the duo was able to pretty effectively layer their beats to turn out a very impressive, mostly polished jam. Fallon's love for rapping and Smith's actual career in rapping mixed surprisingly well together, and the result was a highly danceable computer-created beat. If we get that iPad app, will Smith sing with us? Maybe?
