Holiday Trademarks: THANKSGIVUKKAH? Yes, Thanksgivukkah. Loyal fans of my Holiday Trademarks series (Halloween, Thanksgiving, Winter Holidays Part I, Winter Holidays Part II, and Happy New Year!) must think I’m getting pretty desperate. But since the next Thanksgivukkah won’t happen until the year 79,811, and since I was planning on retiring this blog on my 75,000th birthday no matter what, I guess we should talk about this “event” and its trademark implications.
