Seinfeld producers had to force audiences to laugh at Kramer's eccentric physical comedy during early tapings because the studio crowds were actually genuinely terrified of Michael Richards' aggressive, unpredictable energy.

The showrunners actually had to employ professional laughers in the audience to signal that his bizarre outbursts were meant to be comedic rather than a sign of imminent violence. It is a brilliant reminder that the line between a beloved sitcom neighbor and a deeply unsettling home invader is entirely dependent on a laugh track. Without that audio cue, the entire series just plays like a grim documentary about three selfish New Yorkers tolerating a deeply unhinged man who constantly steals their food and destroys their personal property
