"Soda" joke

Once there were three turtles.

One day they decided to go on a picnic.

When they got there, they realized
they had forgotten the soda.

The youngest turtle said he would go home and get it
if they wouldn`t eat the sandwiches until he got back.

A week went by, then a month, finally a year,
when the two turtles said,"oh, come on, let`s eat the sandwiches."

Suddenly the little turtle popped up from behind a rock and said,

"If you do, I won`t go!"
