The Avengers: Infinity War cast are currently on the promo trail for the latest installment in the superhero franchise, which means that they're doing the rounds on late night talk shows.

It also means that a few interesting facts about various cast members are coming to light, as we saw on Jimmy Kimmel Live last night.

Enlisting Tom Hiddleston, Mark Ruffalo, Scarlett Johansson, Dave Batista and Danai Gurira in a 'Guess the Avenger' gameshow-type quiz, Kimmel made each person guess which of their castmates each fact was related to and it turns out that Scarlett Johansson has a pretty funny story about flashing a complete stranger in an airplane bathroom.

Basically, always remember to lock the door, people.
