Will Smith, Helen Mirren, and Martin Freeman are some of the most recognizable celebrities in the world, but please don't talk to them while their in the bathroom.
During an appearance on "The Graham Norton Show," the three stars shared their weirdest experiences of being approached by fans. All three agreed that the bathroom is not the time to talk to them.
"When you get recognized in a queue for the toilet ... that is not an easy place to be recognized. You're stuck," Mirren said. "Knowing everybody is going to be listening is mortifying."
Smith chimed in, saying that it is equally uncomfortable when he is standing at a urinal and a fan will want to strike up conversation.
Freeman agreed and shared his own story from his time on the original British version of "The Office."
"I was at a gig years ago. I was at the urinal," Freeman said. "There were two guys and they both clocked me and looked at each other and went, 'Has he got a big one?'"
Smith also shared a story about being recognized in a remote village in Mozambique. During the filming of "Ali," Smith was walking through the village -- which had no electricity or running water -- when a woman washing her clothes in the river shouted out "Big Willy!"
