What is that between her legs?

Two Mexican guys are in a bullfighting stadium, when they notice an attractive young lady wearing a short dress and her legs spread wide open.
The first said to his companion, "Eh, Juan, check out the chiquita over there, she got mucho hairy pussy."
"That's not pubic hair, you idiot, she's wearing sexy black panties!" replied the second.
They argue about this for about ten minutes before they decide to send a young boy to sneakily take a look and settle the argument for them. All of a sudden they hear him cry, "Caramba!" and he comes running back to the two men.
They ask, "So what was it, hair or panties?"
"Neither," replies the boy. "It's flies!"

You think that was seriously unfunny? This one's worse!
