You've heard of the phrase "fans disguised as empty seats"? This sets up a visual gag early in this Impossibles adventure when the band plays a gig for the benefit of the Secret Service. However, the party is spoiled by a villain known as "The Puzzler" (not to be confused with another villain by that name, played by the distinguished Maurice Evans, who was a 1-shot opponent for Batman around the same time). Rally-ho!
If ya wanted a serious menace on Saturdays, ya had to watch Superman or Space Ghost. This was twice as campy as Batman, sometimes not in a good way.
