One day a family of squirrels and a family of skunks are crossing the road...

...a car drives by and hits them. The only survivors was a baby squirrel and skunk and from that day on they became the best of friends. Years later, they're walking through the woods together:

Squirrel: Hey, have you ever wondered what we were?

Skunk: Yes, I have.

Squirrel: How about we take a guess what we are, think of a few things that might make us that animal.

So they pause to think for a bit

Squirrel: I'll go first! So, I really like nuts, I can be crazy at times and I have a bushy tail, so I must be a Squirrel!

The skunk agrees, then ponders for a bit

Skunk: Hmm, well let's see here. I am not entirely white, but I am not entirely black and I smell bad, so I must be a Puerto Rican.
