Jay Leno Subs For Jimmy Fallon In Surprise 'Tonight Show' Return

Longtime host takes over the monologue to help 'injured' Fallon.

When a late-night host suffers an injury in the middle of a monologue, who do you call? 

If you're "Tonight Show" host Jimmy Fallon, you turn to your predecessor: Jay Leno. 

Fallon faked a hamstring injury at the top of the monologue and asked if someone could "tag in" for him. Leno, who has a new show called "Jay Leno's Garage" debuting tonight on CNBC, answered the call.

Check it out in the clip above.
