Charles needs to stop using Hal!
Seriously, I don't understand why Charles keeps using Hal in his stings.
For those who don't remember, on one of the episodes, Hal had been caught stealing. Somewhere along the way, Charles decided to use him as one of his mystery diners.
The first time, Hal couldn't keep away from the booze. Then on the episode I just saw the other day (where he was supposed to be a customer waiting for a meal delivery), he fell asleep and only woke up when the producer went and shook him.
