A warning printed on the side of
coffee cups to warn
users about possible
danger. Unfortunately, those that need this so-called
drool-proof explanation are probably not up to date on what "
hot" means, and of the risk that these "hot contents" pose to them.
Other classics include "
Do not expose your LaserWriter to open fire or flame".
A better warning incorporates humor and information, such as "
Do not look into laser with remaining eye".
