"14 inches" joke

A big Texan ambles into a Dallas men's room and does a double-take at the little guy standing at the next urinal. He's holding his "snake" with two hands and smiling.

The Texan asks "How long is that snake fella?"

"14 inches."

"Is that 14 inches soft?"

"Yes."

"Well how long is it when it's hard?"

The little guy answers proudly, "I don't know - it takes so much blood, I faint!"
