The narrator telling about the events, especially in the first episode of the 1st season. This is courtesy of the English hearing captions in the DVD. Even though it's trying to help, just listening to it and watching most of the scenes sounds funny.
Des and Jake's interaction is usually made of funny:
Jake: Why is it that whenever I talk to you, I want to punch you in the face?!
All of this has nothing on Jake and Malachy's snarkfests, however. Good grief.
Take, for example, the instance when Jake nearly gets himself killed (again). Malachy starts railing at him, and Doyle retorts "I'd ask you to come down and help me, but of course you'll never get your walker down here!"
There's another instance when Malachy is just getting out of jail, and Doyle asks him how it went. Malachy's response? "Dandy, they're talking about naming a wing after you."
Des, looped up on painkillers and trying to stealthily peer down a med student's blouse (after calling her an angel and generally babbling).
Bruce thinking Jake, Des and Malachy were hitmen because they were standing in the road in front of his house "trying to steal those snow... sled... machine... things."
Martin drugging and kidnapping Rose. Again. Malachy gets him back in the end by drugging him right back and leaving him passed out on an armchair.
Also, his being shot in the behind for gambling too much... and then shot again. Probably because he deserved it.
Des figures out that Tinny's back in town, then slams the computer shut as Malachy walks in. When Malachy asks him what's wrong... "I got hit by a car and I'm on drugs. *Nonchalant shrug*"
Jake tells Leslie that the case he's in has just gotten bigger after being humiliated by his ex-RNC colleagues when he was caught naked and cuffed.
"What are you two whispering about?" "Nothing. ...Des has fleas." "I don't have them anymore!"
Jake accidentally holds up a bank in "High School Confidential", resulting in a media frenzy and the entire police force arriving at the station.
How Des scares off an attacker: runs at him screaming and waving his arms like a windmill.
Jake: What the hell was that?!
Des: ...the element of surprise!
Jake and Maurice butting heads when they were telling the RNC about what happened to Leslie and Hood. Maurice makes Jake look like a wuss, idiot and a chicken. Jake makes Maurice looks worn, tired and not neat with his clothes. In addition, Jake looks tough and confident in his stories while Maurice looks cool and sophisticated in his stories.
