OMG. Jimmy Fallon has been on a lot of fake TV shows in his time hosting The Tonight Show, but we haven’t seen him break this much since Saturday Night Live!

Ch-ch-check out the video (above) to see the veteran funny lady show Jimmy a thing or two about staying in comedic character!
Also, she slaps him. A lot. It’s pretty great.
