I have run across two Tonight Show with Jimmy fallon clips today that show that Fallon is great at getting his guests do something different. Kevin Bacon recreates the final dance scene from Footloose after Jimmy announces that dancing has been outlawed on the Tonight Show. Jimmy sings The Lion Sleeps Tonight with Billy Joel using an iPAd to loop the background vocals.
I am rarely up to see the Tonight Show, but I am enjoying all of these clips. I think we can safely say that Jimmy Fallon is Jay Leno.
