the.com/clown car

means A chaotic situation, group, or organization that keeps producing far more absurdity, incompetence, or people than its size should reasonably allow.

from Rooted in the literal circus act — a tiny car that disgorges an implausible stream of clowns, a staple of circus clowning for well over a century. The physical gag itself likely grew out of older circus and vaudeville traditions of comic overcrowding, but it was the rise of the automobile in the 20th century that gave clowns a new prop to stuff themselves into. The figurative use — applying 'clown car' to inept committees, campaigns, or companies — is modern slang, taking off especially in political commentary from the later 20th century onward, where 'it's a clown car in there' became shorthand for an organization absurdly overstuffed with incompetence.
