For obvious reasons, no name now.

What I have done in the past (quite often, actually) is to send email to friends that looked like it was in some sort of code, but include the name of a supervisor/owner/boss that I thought was really dumb, or did stupid things. It might look like this:

wundhyrek fuy rewqzoom tom jones hhlkitregda . . .

Then sit back and wait. Someday I'll write a book about the reactions!
