Ahchoo is the tritagonist of Mel Brooks' Robin Hood: Men in Tights. He is played by comedian Dave Chappelle. He is a foreign exchange student from Africa. At the end of the movie Ahchoo is made the new Sheriff of Rottingham. At first the people don't think it's a good idea, but Ahchoo responds with, "And why not? It worked in Blazing Saddles!"
A running gag throughout the film is that whenever someone says his name, another person says "Bless you!"
