Joke

I recently saw a distraught young lady standing beside her car.

"Do you need some help?" I asked.

"I knew I should have replaced the battery to this remote door unlocker," she explained, exasperated. "Now I can't get into my car. Do you think they (pointing to a convenience store a couple blocks down) would have a battery to fit this?"

"Hmmm, I dunno. Do you have an alarm, too?" I asked.

"No, just this remote thingy," she answered, handing it and the car keys to me to inspect.

I took the key and manually unlocked the door. "Why don't you drive over there and check about the batteries. It's a long walk."
