"I don’t think I can continue," Fallon said, "but of course, here at The Tonight Show, the monologue has to go on, so I think I’m gonna have to sub out. Can someone tag in for me please?" Thankfully, Fallon had the perfect sub waiting in the wings: former Tonight Show host Jay Leno!.@JayLeno tagging in! #FallonTonight#LenoOnFallonpic.twitter.com/PJB7VCeRR8 — Fallon Tonight (@FallonTonight) October 7, 2015WATCH: Kaley Cuoco Completely Loses It While Playing Trivia With Adorable PuppiesLeno was more than happy to tag in for a few jokes, some of which, oddly enough, wouldn’t have been out of place during the former host’s tenure on the show."The election’s getting nasty. Did you see this, Ralph Nader called Hillary Clinton a corporatist and a militarist," Leno set up. "Isn’t that unbelievable? Ralph Nader’s still alive?""After that last debate, Marco Rubio being called the best communicator in the Republican party," the former Tonight Show host deadpanned. "Which is kind of like being the smartest Kardashian."

"I got one, I got one," he chimed in, joining Leno onstage. "The economy is so bad, 50 Cent just changed his name to Nickelback."WATCH: Tom Cruise Goes All Out Against Jimmy Fallon in Amazing Lip Sync BattleTom Cruise Pays Tribute to 'Risky Business', 'Top Gun' in 'Tonight Show' Lip Sync Battle This video is unavailable because we were unable to load a message from our sponsors.
