You will find some support online for today being 'Is' Day or The Meaning of 'Is' Day.
It was on this day in 1998 that President Bill Clinton's testimony to a grand jury included these amazing sentences: "It depends upon what the meaning of the word 'is' is. If the—if he—if 'is' means is and never has been, that is not—that is one thing. If it means there is none, that was a completely true statement."
The Blog of Days, being squarely located in the Family Section of the Internet, will not go into details about the Monica Lewinsky matter. It is enough to recount that Mr. Clinton said on January 26, 1998, "I did not have sexual relations with that woman, Miss Lewinsky. I never told anybody to lie, not a single time; never. These allegations are false." However, on the evening of August 17, 1998, after his grand jury testimony, a few weeks after the infamous blue dress was turned over to the special prosecutor's office, Mr. Clinton was back again on TV, acknowledging (quoting now the linked Wikipedia article) that his "relationship with Lewinsky which was 'not appropriate.'"
While there is support, therefore, for calling today 'Is' Day, the whole thing strikes us as rather tacky and not a thing to be celebrated.
We asked our crack research staff to come up with an alternative. They reported that brownielocks.com suggests that today could also be Hug Your Boss Day -- and then they wouldn't stop snickering.
