Jimmy Fallon surprised his audience, as well as viewers at home, on Tuesday night when he brought Jay Leno back to The Tonight Show.

Fallon started the show as usual–easing into his monologue. Then he suffered an injury.

“I think I pulled a hammie on that one. I don’t think I can continue,” Jimmy Fallon said. “I think I’m going to have to sub out. Can someone tag in for me please?”

That’s when Jay Leno took the stage to an abundance of loud applause. He took over the monologue, immediately launching into several one-liners about presidential candidates.

“You know, a lot of people think that when the Republican feud begins to clear, it’ll be between Jeb Bush and Donald Trump–kind of like the race between the tortoise and the bad ‘hair.'”

Hillary Clinton and Bernie Sanders got their fair share of time during the monologue, too.

Jimmy Fallon rejoined Jay Leno on stage when he started mocking the state of the economy.

“(The economy) is so bad even the Kardashians are losing their ass!” Jay Leno cracked.

“The economy is so bad Hillary Clinton wants people to look through her deleted e-mails to see if there’s anything from that Nigerian prince,” Jimmy Fallon added.
