You know, they remind me of that 'Dead Presidents' movie, too, LOL.
I suppose mimes, dance, puppet and similar ministries are eminently mockable - like playing the guitar or recorder - easy to do badly but hard to do well.
There's this one group I see sometimes, more than dancers but not quite mimes (no face paint) who have gloves on - not MJ 1-hand style, but both hands...
