Arson, Murder, and Jaywalking: After Mrs Doyle goes on about profanity, she finishes with something that technically has no profanity, but is still adult-age-rating-inducing because of its sexual implications:
Mrs Doyle: 'Ride me sideways' was another one!
Ax-Crazy: Tom, as usual. He robs a post office in one scene:
Corpsing: Mrs. Doyle lists off vulgar turns of phrase in a certain author's books. After Ted escorts her out, she calls through the door "'Ride me sideways', was another one!" This was unscripted, and Dermot Morgan is evidently trying his hardest not to lose it.
Downer Ending: Graham Linehan called the episode "terribly sad", stating that Ted should really be married to Polly, while Arthur Mathews acknowledged that they would probably get on quite well as a couple.
The scene where Ted gets picked up by Tom was inspired by Thunderbolt and Lightfoot. In one scene, Thunderbolt is picked up by a crazed car driver who opens the back of his truck to reveal a group of rabbits, which he then shoots; this character inspired the Tom character.
