Three tortoises, Al, Jeff and Jake, decide to go on a picnic. So AL packs the picnic basket with beer and sandwiches. The trouble is the picnic site is ten miles away so it takes them ten days to get there.
When they get there Al unpacks the food and beer. "Ok Jeff Give me the bottle opener."
"I didn't bring it," says Jeff. "I thought you packed it."
Alan gets worried, He turns to Jake, "Did you bring the bottle opener??"
Naturally Jake didn't bring it. So they're stuck ten miles from Home without a bottle opener. Jeff and Alan beg Jake to go back for It, but she refuses as she says they will eat all the sandwiches.
After two hours, and after they have sworn on their tortoise Lives that they will not eat the sandwiches, she finally agrees. So Jake sets off down the road at a steady pace.
Twenty days pass and she still isn't back and Jeff and Alan are starving, but a promise is a promise.
Another five days and she still isn't back, but a promise is a promise. Finally they can't take it any longer so they take out a Sandwich each, and just as they are about to eat it, Jake pops up from behind a rock and shouts........
"I KNEW IT!......I'M NOT GOING!"
