Timely Yo-Yo Tricks

In the November 23, 1929 issue of The New Yorker, a helpful reader (Mary Rose Himler) submits a timely list of popular yo-yo tricks:

The Moanin' Low
The Touchdown
The Standing Sitting Standing
The Lindbergh Loop
The Double Trouble
The Lowdown
The Boop a Doop
The Four Easy Marx Brothers

Who would have thought that trick names would reflect current events? Somebody needs to do a study on this through the last eighty years, to see how the names have changed.
