A masked man walks into a bank and holds it up at gunpoint to rob the bank.
In the process of robbing the bank, his mask fell off.
He quickly put it back on his face and asked the teller directly ahead of him if she saw his face.
She admitted that she did, so he shot and killed her.
He then turned to the teller that was beside the one her just killed and asked if she had also seen his face.
She said that she did and he shot and killed her too.
He then turned to a man, a customer who just happened to be in the bank when the robbery was taking place.
The robber asked the customer if he had seen his face.
The customer replied, “No, but I’m pretty sure my wife did.”
