A family of tortoises (Mamma Tortoise, Daddy Tortoise, Grandpa Tortoise, and Baby Tortoise) decide to go on a picnic. They pack up their basket up and begin their journey to the park. One week later, they get to the park, unpack the basket, and realize they've forgotten the salad dressing! They plead with Grandpa Tortoise to go back and get it.
"No way!" Grandpa Tortoise says. "The trip'll take me two weeks there and back. You'll start on the food without me and it'll be all gone by the time I've returned!"
After much reassuring that they won't touch the food, the family finally gets Grandpa Tortoise to retrieve the dressing. They send him on his way.
Two weeks later, the Tortoise family is getting hungry but there's no sign of Grandpa Tortoise.
"I'm sure he'll be here soon," says Mamma Tortoise. "And we promised we wouldn't start without him."
Another week goes by and Grandpa Tortoise has still not come back. The Tortoise family is beginning to starve.
"I know we're all hungry," says Mamma Tortoise. "But we promised so I'm afraid we'll just have to wait."
Another week goes by and still no sign of Grandpa Tortoise. The Tortoise family is slowly starving to death.
"I can't take this anymore!" says Daddy Tortoise. "We can't starve ourselves waiting." He grabs the sandwiches and starts passing them around.
As Daddy Tortoise takes his first bite, Grandpa Tortoise pops up from behind a bush and says, "I KNEW YOU WERE GOING TO START WITHOUT ME! I'M NOT GOING."
