My late, lamented - and loved- friend, Linda Miller, always sent homemade cards to people on the holidays. (Halloween, Christmas, and even Valentine's Day.) She once sent out the artwork below as a 2005 Halloween card. Below it is the punch line she wrote for the card:
"Whoever it is, don't let them in-----and Fritz, if it's those rotten kids again tell them once and for all that we haven't got any candy!"
