I have a Jackalope mounted on the wall of our ranch in Benchley, TX. Well, it may actually be a Chupacabra, I was really drunk on Lone Star beer and tequila when I shot it. We were just shooting anything that moved, then took what was on the ground to the taxidermist. Who knows what that thing is?

Glad hunting season is starting, anyone want to come down and go hunting with us in South Texas?

...er, um, ah....I think I'll pass on the hunting invitation. I seem to recall a hunting incident in the news a few years back on a Texas ranch involving a Mr. Cheyney. Since then, I've retired my rifle and hunting boots.

Hey Mitch4t, that's the trip I was talking about, funny you should bring that up.
