These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Thin Blue Line
Accidental Innuendo: This example from "Kids Today", in which he fondly describes his childhood Mechano sets, much to Habib's amusement:
Fowler: They'll never know the joy a young lad can have sitting alone in his room... with his tool in his hand, tightening his little nuts.
Grim: "It's my arse on the line and I don't want a cock-up!" and many variations.
Raymond and co. busting the pub lock-in in "Alternative Culture" after Grim refuses to let Habib off for withholding evidence to protect her sister. Grim and Boyle try to escape through the bathroom (which Boyle claims is an "old coppers' trick"), only to find Raymond waiting for them.
Raymond: The problem with old coppers' tricks, Constable Boyle, is that old coppers know 'em.
