Thing To Do Today: pogo.

You can pogo with a Pogo Stick, if you can find one:

but it's easier and much safer (especially for the over-eighties) to pogo without one.

It just involves jumping up and down on the spot.

To pogo with style you should put on some very loud music (probably not by Beethoven), flip your hair backwards and forwards (if you have any) and try to look earnestly ecstatic.

Having a heart-attack half-way through isn't at all in the spirit of the thing, so do take care.

Thing To Do Today: pogo. This word was first used in 1921 and comes from the trade name of the Pogo Stick. Where that name comes from is not accepted as proved by the dictionaries, but the Pogo Stick was invented by the Germans Max Pohlig and Ernst Gottschall, so if the word isn't based on their names then that's a heck of a coincidence.
