* From "The Killings at Badger's Drift":
-->'''Barnaby''': Troy, you are about as politically correct as a Nuremberg Rally.
* Cully's cat, a Russian Blue named Killmowski.
* Troy and Jones being introduced, after the former nearly runs the latter off the road. In fact, Troy's driving in general is pretty hilarious in and of itself.
* ''Faithful Unto Death'', when Barnaby and Troy visit charming old ex-actress Elfrida Molfrey and her brother Bunny, and Barnaby has a couple of cupcakes. He spends the next couple of scenes acting most peculiar; randomly chuckling at nothing, walking along the tops of walls, and calling Troy things like "Mon Brave". [[spoiler: He later realizes that the cakes were laced with cannabis.]]
* "Dead in the Water", during which Scott and Barnaby must often cross rivers, and the only way to do so is via rowboat (and guess who gets to row...) When Scott arrests a guy, he brings him back via rowboat, with an unbelievably smug expression as he finally gets to sit back.
* There's a case in a village which has people who like to role-play. At one point Barnaby is walking in the woods and hears a woman calling for help, Barnaby finds her, in a gown fit of a princess, and there's nothing wrong with her. A man turns up with a gun and dead rabbit in hands and seems confused about Barnaby being there and then a second man with a camera arrives and when the first man asks who the second man is and Barnaby tells him that it's her husband. The man with the gun says, "Her Husband", in a disbelieving voice and then turns round and runs off.
** That same episode ends with Tom reading in bed while Joyce finishes her preparations to join him. She runs down the list of sexual role players in the village commenting that she could never stomach either the 'maiden in distress' scenario or the 'perfect wife' one but thought she could have some fun with the dominatrix role. Tom looks up wide eyed and his book snaps closed just as the we go to dark.
* From "The Axeman Cometh":
-->'''Barnaby''' How old do you think I am?\\
'''Jones''' I've done speed dating, not carbon dating.
** Later on, after Jones and Barnaby pass a bongo player in the street.
-->'''Jones:''' Can I arrest the bongo player?\\
'''Barnaby''' Only if you promise to break his fingers.
* Troy telling Barnaby where the body is:
--> "What, where the all the blood and police photographers are? Thank you Troy."
* "A Talent for Life" has [[SeriousBusiness a woman explaining the nuances of fly-fishing and why it led to her slapping another club member]]. Troy's panicked expression of slack-jawed "wuh?" throughout is hilarious.
* This exchange from “Murder on St. Malley’s Day”:
--> '''Barnaby:''' Smothered by a meat pudding, flattened by a roller, bashed about the head...\\
'''Troy:''' Think it could be accidental, sir?\\
'''Barnaby:''' No time for jokes, Troy.
* From “Days of Misrule”:
--> '''Jones:''' Don’t look now sir, but we’re being watched.\\
'''Jones:''' One o’clock, big man in red.\\
''[Barnaby looks around to see an inflatable Father Christmas on the roof.]''\\
'''Barnaby:''' Oh, you’re full of fun today, Jones.\\
'''Jones:''' I like Christmas, sir!
* "The Green Man" has Troy make an unfortunate comment about an old case:
--> '''Troy:''' Before your time then.\\
'''Barnaby:''' It ''still is'' my time, Troy.
* "Sins of Commission": Scott nearly gets run over while chasing after a thief who broke into the murder victim's home. Once he gets back and is still brushing himself off, we get this:
--> '''Barnaby:''' Do you notice what else is missing, detective?\\
'''Scott:''' [[ButtMonkey Sympathy]], sir?\\
'''Barnaby:''' No, [[ItMakesSenseInContext the piggy bank.]]
