Aaron encountered a Catch-22 while signing up for wireless access. For you logicians out there, see if you can follow me. Signing up for wireless access (C) requires you to enter your credit card over a wireless connection (A). You should never transmit credit card information wirelessly (B). Therefore, ((A ^ B) => C), but (A => !B) and (B => !A). Ergo, you can never sign up for wireless access. Also, note that it only warns you about this after you've already submitted your credit card information.
