I think I have a new e-mail signature.

Confidentiality Note: The information contained in this message, and any attachments, are transmitted in plain text for everyone to see while going across untrusted networks and stored on mail servers and often archived for future reference under the pretense of national security. Although this message is intended solely for the person or entity to which it is addressed, there has been absolutely no attempt made to actually enforce this despite the long standing availability of PGP and other encryption schemes. If you received this in error, please forward this message to everyone you know (except the sender) and laugh hysterically at the misguided notion that unencrypted e-mail is private.
