"Celebrity Juice" host Keith Lemon provides a different reason for the bandaged hand each time he is asked this question. Reasons given have included everything from covering an unsightly tattoo to a having a sports injury.
Keith Lemon, a character portrayed by British actor Leigh Francis, is a man obsessed with women. Lemon seems to create a new story behind the bandage prop with each interview, having claimed a kangaroo attack and a really bad tattoo. As actor Francis wears the bandage every time he appears in character as Keith Lemon, many people suspect the bandage provides a reminder to stay in this rather unsophisticated character.
