A switcheroo is a sudden unexpected variation or reversal, often for a humorous purpose. The bed trick is used in Roald Dahl's story "The Great Switcheroo". Keane switched with Scott Adams of "Dilbert" in the 1997 comic strip switcheroo. It would rather kill off a main character than pull a lame switcheroo. "The Great Switcheroo" is a short story by Roald Dahl. Vincenzo visits Diane at the orphanage and tells her about the switcheroo.
