The Fourth week of May is:

International Pickle Week

Here's some info about this "event", first "celebrated" in 1948.

Teach your dancers Pickle Up a Doodle...and make sure they get a fun badge (A088 pickle up a doodle 122 Dancing with no mistakes to Windsor record #4823.). BTW, did you know that Theresa Brewer originally recorded Pickle Up a Doodle?
