So there's a family of rabbits on the side of the road...

Mommy, Daddy, and Baby Rabbit.
They're hopping across and BAM, a truck runs over Mommy and Daddy, but Baby makes it across.

Back on the other side, there's a family of skunks. Mommy, Daddy, and Baby Skunk.
They go waddling across the road and BAM, a truck runs offer Mommy and Daddy, but Baby makes it across.

So Baby Rabbit and Baby Skunk are sitting there on the side of the road.
The rabbit starts crying. The skunk asks him what's wrong, and the rabbit says "Well, my parents are dead and I'm all alone. I don't know where I'm going, I don't remember where I'm from, I don't even know what I am!"
The skunk looks him over and says "Well, let's see, you've got floppy ears and a cotton tail and hop when you walk, you must be a rabbit!"

The rabbit feels his ears, looks at his tail, takes a hop, and says "You're right, I'm a rabbit. I feel better!"

So they sit there a little longer, but the the skunk starts crying. The rabbit asks him what's wrong, and he says, "Well, my parents are dead too! I'm all alone, I don't know where I'm going, I don't remember where I'm from, I don't even know what I am, either!"

The rabbit looks him over and says, "Well...
You're not white and you're not black, and you smell kinda bad,

You must be a Mexican!"
