A set designer, actor and stage manager are in the prop room. The actor accidentally rubs a prop lantern as he passes by it.
A Genie appears and says, "I shall grant you three wishes. One for each of you.
The set designer says, I'd like to go to Ancient Greece to study how theatres were built.
Poof! The Genie sends him off.
The actor says I'd like to go to Elizabethan London and meet Shakespeare.
Poof! The Genie sends him off.
The stage manager looks at his watch and says, "I'm going to need them both back in 5 minutes..."
