We have those roaches here; Southeast Texas. I've been attacked in the shower twice in the last three months. I heard noises in there this morning, but when I got the flyswatter and opened the door, nothing there. Was I ever relieved!

My ex got stung by a scorpion in West Texas. It crawled on him while he was sleeping and apparently he swatted at it involuntarily.
