The Sherlock star likes embarrassing pals

Cheeky Benedict Cumberbatch loves a good prank – especially when there’s free cake involved.

The Sherlock actor has confessed in a Reddit Ask Me Anything web chat that he likes to play a practical joke on friends that enables him to get dessert as well as a good laugh.

Anytime you’re in a restaurant with a group of friends and one of them goes to the restroom or bathroom (presume there are many nationalities involved in this AMA), tell the waiter that it’s that person’s birthday,’ writes Benedict, 37.

Not only is it fun to embarrass the hell out of the poor victim, but you get free cake in the bargain.
