Sometimes, the pair will claim to reveal a secret of how a magic trick is done, but those tricks are usually invented by the duo for the sole purpose of "exposing" the method to the audience, and therefore designed with more spectacular and theatrical methods than would be practical in a "conventional" magic trick. For example, during their NBC "Off the Deep End" special, an escape act was performed where Teller was placed into a wooden box that was then put into shark-infested waters. The live audience believed Teller to be inside, but the television audience was shown that Teller escaped the box through a trapdoor in the bottom before it was placed in the water. He continued to read a magazine and eat a snack while awaiting his cue. Often a trick will be presented as if to explain it to the audience, only for a more elaborate version to be performed. In a segment of "Bullshit!", Penn & Teller demonstrate the illusion of sawing a woman in half, only for the saw to fall and "accidentally" cut the woman in half again.
