Weighing Scales

On the way to the concert last night I put a 20p in a weighing scales.
Now I know I've been watching my weight recently, but when it said I was 6 stone, I knew the machine was faulty.
No getting that 20p back!
It reminded me of the time I pulled the ticket out of the machine and was distraught that I'd put on 2 stone.
Jeez, I thought, must cut out on the pizza!
I checked the ticket again and was surprised that I'd shrunk 3 inches in height, too.
I was shrinking away, I thought!
It dawned on me then that the last guy had left his ticket in the machine.
When my ticket came through, I'd actually lost a pound.
See, a happy-ending story for you.
