Basil the Rat (a.k.a. Rats) - S2-E6
Trivia: Melody Lang, who plays Mrs. Taylor in this episode, is Andrew Sachs' wife.
Trivia: In an homage to the king of Hawaii-based cop shows, Hawaii Five-O, Don Ho tells MacBride and Ryan at the end that if they ever break up his night club again, he's going to call McGarrett. Ryan gives MacBride a baffled look and just before the freeze-frame, queries, "Who's McGarrett?"
Trivia: All through the run of the first season, the multiple banks of red, white, and black input keys have no numbers, letters, or symbols of any kind, but information can be accurately input.
Trivia: The blue Ford Cortina squad car seen in series 1 and 2 has the reg number NHK 296M. Sometimes it is fitted with a false number DLO 97M on the front (as has been noted as a mistake). The programme makers had been supplied with two cars from Ford, this Cortina and a Consul GT. The Cortina was fitted with this false plate to make the squad look like it had more cars, and only one number plate (the white front one) was made up to keep costs down, as the Sweeney had a small budget. In the series 3 episode "Pay Off" DLO 97M is on a white Cortina, in series three the same Triumph 2000 is seen with number plates TPA 931N and UUV 931N - again it is the same car with different number plates.
