We were sitting at a redlight once and some cop pulled up to our left and was eyeballing my husband. So he looks over and asks the cop "Can I help you?" 

The cop responds, "Just checking to see if you're wearing your seat belt." (Sure he was, while he's running our plates on his laptop) 

My husband asks him, "Does that law apply to everyone?" 

Cop, "Of course." 

"Then 'click it or ticket', Officer," my husband points to him. That's when the cop looks down and notices he's not wearing his own seat belt. He gets all red faced and puts it on then tears ass out of there once the light turned green. 

It was great. We laughing so hard.
