Dr. Wacko:
I am interviewing astronaut Albert EinFrommage, who
returned from a space voyage which approached the speed of light. I
understand that he actually traveled backwards in time for a moment as
he approached the speed of light. Captain EinFrommage, can you describe
what happened.

Captain EinFrommage:
Well, we were
approaching the speed of light. I suddenly had the urge to defecate so
I went to the toilet. As I was sitting there, we approached the speed
of light and I was appalled at what I saw. There was evidence that we
were traveling backwards in time.

Dr. Wacko:
How could you tell?

Capt. EinFrommage:
My turd went back up my ass.
