So I come out of the bathroom of the Dollar General. I have the key-attached-to-ruler in hand, which unlocks the door. A blonde looks at me as I hand her the key.

"What's the key for?" she asks with concern.

"For the bathroom"

"Well, what do I do with it?"

"You unlock the door."

"With the key?"

"Yes"

"And then what?"

"You go to the bathroom."

"So how do I unlock the door?"

"With the key..."

"How do I put the key in the door and unlock it?"

"Forget it...Have a nice day..."
