I may just have to resort to doing something like this.
Heinlein was also known for sending out quirky holiday/special occasion cards as well. Surrounding the outer edges of the card with dates that he could circle, they’d go a little something like this:
We wish you
…a Happy New Year!
…a Merry Christmas
…a Joyful Chanukah
…a Bountiful Year of the Pig/Rat/Ox/Tiger/Hare/Dragon/Snake/Horse/Sheep/Monkey/Fowl/Dog
(It goes on, with other holidays as well such as the 4th of July, a ritious Guy Fawkes Day and a safe Lunar Landing (notice the capitals there.)
A brilliant idea from a brilliant writer if you ask me.
