Suggestion for a witty Emacs command for a mug?

[Jeanne Rasata]

Hello, youz,

The FSF is trying to come up with a cool Emacs-related design/theme
for one of the mugs we sell.  One idea is to put a witty command on
it.  Do you have a suggestion for what could be a witty command, or
sequence of commands?  Or maybe something else Emacs-related?
If you do, please let me know!

Thanks for your time.
Sincerely,
j.
