Tom Robbins said this quote

The clown is a creature of chaos. His appearance is an affront to our sense of dignity, his actions a mockery of our sense of order. The clown (freedom) is always being chased by the policeman (authority). Clowns are funny precisely because their shy hopes lead invariably to brief flings of (exhilarating?) disorder followed by crushing retaliation from the status quo. It delights us to watch a careless clown break taboos; it thrills us vicariously to watch him run wild and free; it reassures us to see him slapped down and order restored. After all, we can condone liberty only up to a point. Consider Jesus as a ragged, nonconforming clown--laughed at, persecuted and despised--playing out the dumb show at his crucifixion against the responsible pretensions of authority.
