Two birdies...
 

Two robins were sitting in a tree. "I'm really hungry," said
the first one. "Me too," said the second. "Let's fly down and
find some lunch." They flew to the ground and found a nice
plot of plowed ground full of worms. They ate and ate and ate
and ate 'til they could eat no more.

"I'm so full I don't think I can fly back up to the tree."
said the first one. "Me either. Let's just lay here and bask
in the warm sun," said the second. "O.K." said the first. They
plopped down, basking in the sun. No sooner than they had
fallen asleep, a big fat tom cat snuck up and gobbled them up.

As he sat washing his face after his meal, he thought, "I love
baskin' robins."
