Jimmy Kimmel knows that free food is one of the greatest gifts you can give.
"Thank you Jimmy Kimmel and staff for the 2nd Ave Deli lunch. Class act. Watch Jimmy every night at 12:37 only on NBC," Fallon posted on Instagram.
Anybody else suddenly hungry?
"congratulations to my dear, sweet @jimmyfallon- a formidable rival and an incredible lover," Kimmel previously posted on Twitter.
NBC officially announced on Wednesday that Jay Leno is exiting The Tonight Show in the Spring of 2014, with Fallon stepping in to replace him. No decision has been made about who will take over Fallon's Late Night job, but rumor is that Saturday Night Live's Seth Meyers is the frontrunner.
"I'm really excited to host a show that starts today instead of tomorrow," Fallon joked.
