OCTOBER 22 IS INTERNATIONAL CAPS LOCK DAY! YOU CAN'T WRITE IN ALL CAPS UNLESS YOU ALSO HAVE AN EXCLAMATION POINT! IT ONLY SEEMS NATURAL!
But of course, writing in all caps does NOT seem natural for me. International Caps Lock Day is celebrated twice a year, on June 28th and October 22. Originally just October 22 since 2000, a second holiday was added to honor Billy Mays, who died on June 28th in 2009 (Thanks, Craig L). Occasionally, someone else will proclaim a different day as Caps Lock Day, so everyone can have another round of fun.
It is also convenient day to look at the work of Don Marquis, the creator of Archy and Mehitabel, who were a cockroach and a cat that appeared in Marquis' newspaper column. Archy loved to type out his thoughts, which were all lowercase because he had to jump on the keys one at a time, and could not deal with the shift key. However, one day he discovered the shift lock key, and the result was the poem "CAPITALS AT LAST," originally published in 1933.
How do you plan to celebraste INTERNATIONAL CAPS LOCK DAY? I sincerely hope it won't be by shouting all day long.
