1. Teased by their peers, but always ratings winners

2. A calling card facial feature


Spiky white hair, meet The Chin
3. They share a love of classic cars


Leno is famous for his beloved garage, but Fieri's collection is pretty baller, too.
4. Both are still road warriors, performing nationally


Even though they are highly visible via television, Fieri and Leno both take their show on the road as often as possible. Leno has continued to perform a grueling number of stand-up dates throughout his Tonight Show run (he keeps the TV money in a vault and spends the stand-up cash), while Fieri has his own tour and also appears at plenty of food festivals.
5. Short stays in NBC primetime


Jay Leno went from The Tonight Show at 11:35 to a disastrous run at 10 p.m. in 2009. It was short-lived because the ratings were so low that local affiliates straight up revolted. Fieri, meanwhile, hosted two seasons of the low-rated game show Minute to Win It.
6. A kinship with Adam Sandler


Adam Sandler and friends were just on Diners, Drive-Ins and Dives to promote Grownups 2. Meanwhile, Sandler is a frequent guest on The Tonight Show, and even gave Leno some controversial advice on air back in 2009 (he told him to go to Fox).
7. A love for fast food


Fieri is no stranger to unhealthy food, and has his own burger chain aboard Carnival Cruise lines. Leno, meanwhile, has always indulged in populist fare, and even worked at a McDonalds when he was young.
8. An affiliation with T.G.I. Fridays

Fieri cut ads for the restaurant chain for two years. Leno did this in 1993.
