It's one of those anecdotes that you're probably more likely to tell when you're a few drinks in, not on national television with the distinct possibility that it'll be seen by potentially millions of people.
But when you're Sir Patrick Stewart, who cares? You can do what you want and that's how last night's Graham Norton went. The veteran actor told a story about how, for many years, Patrick Stewart thought he was circumcised - although his wife disagreed with him.
In fact, he was so certain of it that he even asked a doctor to check it out for him. It's not so much the story as it is Hugh Jackman and Graham Norton barely able to keep it together as Stewart retells it, because Jackman looks genuinely interested - after all, he's spent so many years with the guy, you think you know every story there is about them.
Take a look.
