This is a really good one and it's your first. You show promise. I welcome you to the board with trip 5's. Keep writin' you have good parody senses, well except for the olfactory ones. :)

A guy goes on a business trip to Texas. His business done, he goes back to his hotel's bar, and orders a beer. The Guy behind the bar puts a HUGE pitcher of beer on the bar. The businessman says, "Not that I'm complaining, but why's the beer so big?" And the Guy tending bar says, "Well, everything's big here in Texas." So the businessman drinks the entire pitcher of beer. And then another. And then another. Then he asks the Guy behind the bar, "Shcuse me, where'sh the bathroom?" The Guy behind the bar says, "Go up the stairs and turn right. Now, don't turn left. That's the hotel spa. Go up the stairs and turn right." Unfortunately, the businessman, being drunk, trips over the top step. When he gets up, he's turned himself around. He turns to the right, the former left -- no, that's not a political joke -- and goes into the hotel spa. And he trips and falls into the pool. And remembering what the Guy behind the bar said -- "Everything's big here in Texas" -- he shouts, "Nobody flush!" Proving that John Fogerty really SHOULD have said, "Don't get drunk tonight, it's bound to take your life, there's a bathroom on the right."

I haven't heard or read that joke in a long time. Also, good parody.
