Two magicians walk into a bakery
The first palms 3 donuts. He then snidely challenges the other magician to perform a trick of equal benefit. The second magician then calls the baker and asks for 3 donuts if he'd like to see a magic trick. The baker does his part and provides the donuts. The magician then eats the donuts and exclaims "Ta-Dah." The bakery is angered and asks "Well what's the magic trick?" The second magician replies "Look in my friend's pocket."
How many magicians does it take to pull a rabbit out of a hat?
One. It's a trick question.
Harry Houdini used to use lots of trap doors in his magic act.
He eventually stopped, he was just going through a stage.
