This happened a while ago- back when people sent out Christmas cards and you always got samples of cards to buy. One year I took one of the sample cards, crossed out the message and wrote: "Things were a little tough this year so we're working on cutting back on Christmas expenses. But it's the thought that counts, so Merry Christmas." Mailed it to my brother in-law at his office address with no postage and his home address as return address. Worked perfect too, had to pay his own postage for our Christmas card that year.😈
To me it's funny but maybe you had to be there....
