With his unexpected guests and hilarious skits, Jimmy Fallon consistently raises the bar of the late night game. Last night, the comedian outdid himself when he surprised viewers with an appearance by Sarah Palin.

The politician hasn't been in the spotlight much lately, but is still remembered for famously claiming she could see Russia from her house. In Jimmy's world, it only makes sense that Palin would appear on 'The Tonight Show' in a skit in which she pretends to be besties with the president of Russia, Vladimir Putin.

Jimmy donned his best bald cap and Russian accent for the bit, which culminated in himself and Sarah covering Pharrell's hit 'Happy.' The former vice presidential candidate even threw down a flute solo. As expected, the audience was in stitches.

We love that Jimmy isn't afraid to push the limits or to address serious topics with a sense of humor. He's always original -- and always hilarious!
