THREAD CREEP WARNING:
In the UK at any rate in the old fashioned funfairs ( before theme park white-knuckle rides) there used to be a "cake walk" which was a swaying and bucking walkway where you tried to keep your balance ( a bit like the new pedestrian bridge across the Thames. Presumably the antics of the pedestrians resembled the "minstrel show" dancers? What simple pleasures we enjoyed in the 1950s before television: cake walks, gusts of air up the skirts, Distortin mirrors, dodgem cars, simple carousels, ferris wheels! Nostalgia ain't what it used to be!
