"You put your left leg in,
left leg out,
in, out, in, out
and shake it all about!"
(A song/dance called 'The Hokey-Kokey' - could be just a British thing!)
Man, proud man, drest in a little brief authority, most ignorant of what he’s most assured,
his glassy essence, like an angry ape, plays such fantastic tricks before high heaven,
as makes the angels weep.
William Shakespeare (anticipating George W Bush?)
