You Can't Fix Stupid

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

' Do you need some help?' I asked.

She replied, 'I knew I should have replaced the battery to this remote door unlocker. Now I can't get into my car. Do you think they (pointing to a distant convenience store) 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.

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