Continuity mistake: While Fred and Barney are being chased by the police, in the closeup of the stop/go signal we see two ropes beside the monkey's hand - one controlling "stop" and one for "go", but in the wideshot there's only one rope hanging from the post, apparently controlling both "stop" and "go" signals. (00:19:55)
