Well, Pinch My Bum

How many names can one holiday have? Quite a few, such as Restoration Day, Oak Apple Day, or Royal Oak Day. It was an English public holiday, observed annually on 29 May, to commemorate the restoration of the English monarchy in May 1660. It is also known as Shick Shack Day, Oak and Nettle Day, Bumping Day, and Pinch-bum Day. Each group seems to have their own name and as many ways to celebrate the English monarchy.
