Who Glued Up the Orangutan?

Chihuahua is supervising a casting session for his play about a detective that looks a lot like Sherlock. Three actors are trying out for the main role. One of them, Orangutan, finds himself with a telephone stuck to his ear. Who could have done such a thing? As for Sherlock, our hero is flattered to have a play written about him, but this brings back some bad memories.
