Most of my friends don't bother with April Fool's pranks. To quote my husband, it's like drinking beer on St. Patrick's Day or making love on Valentine's. Amateur Hour. My kids, however are disappointed that his year it occurs during their Spring Break, so they don't get to terrorize each other and their teachers.
For any of you who thought April Fool was a recent phenomenon, you'd be surprized. Thomas Nast drew a famous cartoon in 1864: and it was an old holiday then.
Here's a website with some interesting looks at the history of the holiday: http://www.southcom.com.au/~seymour/aprilfool/april.htm
So tell me...what was your favorite April Fool's Joke?
