COUNTDOWN TO LÜTZEN I: SHENANINGAN

All right, this year's #CountdownToLützen will be a little different than its precedessors... things like dadaistic artwork, and the like... instead of the 30YW-related content of years past. Also, that will make a one-of-a-kind countdown (but there will still be an in memoriam on the 6th, of course; it's only for these five days that unexpected things will happen!).
Starting with this little piece of art below, which I have determined to call shenaningan (from shenanigan and sharingan!)...
