CM Punk was subject to a lie detector test this past week on RAW. It was a rather creative segment that ended in a rumble involving Ryback, The Shield and Miz.
Lie detector test segments could be a strong storyline tool moving forward. Similar to contract signings, the lie detector test is a simple, confrontational method of advancing feuds.
The WWE has multiple candidates for lie detector tests given the abundance of storylines. Strong candidates are involved in scandals or controversial storylines with a payoff in doubt.
