don't mess with texas

So The Librarian and I are once again donating a practical joke to our church's upcoming youth auction. The youth use the money from the auction to fund their summer mission trip, so, you know, when we engage in a little mischief on behalf of a generous donor, we're actually Pranking for Jesus (tm).

To give you an idea of what this involves, here's an account from last year's victim. And here's a summary of some of our other bad behavior.

Last year, our prank brought in $150. So we want to be sure to give our donors their money's worth. Any ideas on what we should do this year?
