Dad Joke

A guy walks into a bar and sees a sign that reads: Cheese Sandwich: $1.50, Chicken Sandwich: $2.50, Hand Job: $10.00. He checks his wallet and beckons to the exceptionally attractive bartender. 'Are you the one who gives the hand jobs?' he asks. 'Yes,' she purrs. 'I am.' He replies, 'Well wash your hands, I want a cheese sandwich.'
