Is it the use of multiple font styles and effects -- bold, all caps, underline, italics -- all in one brief message? Or is it the patient precision: do change inside; don't change outside? I'm not sure. But whatever it is, this sign, posted in a local rink, always makes me chuckle.
Clearly, trying to communicate with those dang hockey players over the years has been exasperating. We've had it up to here.
