All the avengers are sitting in the living room watching a movie
Nat: I kinda miss Russia
Steve: why
Nat: well here, we drive on the right side of the road
Clint: in England you drive on the left side of the road
Nat: yeah
Clint and Nat: and in Russia, road is road
Everyone looks at them like they're crazy
Clint: fast way of getting around, you don't have to wait for people
Nat: caused a lot of car accidents though
Clint: yet somehow every time we go, the car accidents happen right behind us
Nat: I know
Clint: wanna go to Russia next time we go on vacation
Nat: sure

The next time they got vacation time Clint and Natasha took all the avengers to Russia and sure enough all the car accidents happened every time they switched sides of the road
