If people are amused by the game it tends to lie in the uncertainty of pursuit and capture from both sides. Some got pleasure from watching otherwise respected and agile friends blundering about. Some as the blindfolded player got pleasure from the license to approach and challenge anyone at random.
Oh, and of course those who persistently guess the wrong name etc stay blinfold longest and get to blunder about bumping into everybody. Some get frustrated, some helpless with laughter, but some very obviously enjoy persisting in this role.
Whatever else, while the blinfold was still on, it could still legitimately be viewed as a game.
