Alan: Okay... this is the brake and this the... electric.
It gets even funnier when Jake actually starts driving the thing.

Jake: Is it on?
(Jake presses on the pedal and the car suddenly speeds up)
Charlie & Alan: BRAKE! BRAKE! BRAKE!
Episode 7, Judith accuses Alan of speaking derogatory things to Jake about her.
Judith: Alan, have you been badmouthing me?
Alan: B-B-Badmouthing you? To whom?
Judith: To Jake.
Alan: Oh, to Jake. No, why?
Judith: His attitude towards me lately is so disrespectful. I have to wonder where he's getting it from.
Alan: Well I can assure you that I always make it a point to speak highly of you in front of our son.
Judith: What about your brother?
Alan: Oh, with Charlie I'm completely honest.
Judith: That's not what I meant.
Alan: I know. Smug grin
Charlie walks into the scene, holding a bottle of beer.
Charlie: Hey Judith.
Judith: Charlie, have you said derogatory things about me to Jake?

When Judith meets Alan's date, Charlie plays certain notes on the piano in response to what's said. When Judith leaves, he plays Na Na Hey Hey Kiss Him Goodbye's chorus.
Made even better when the voices that usually chorus "mennnn" during the scene changes say "squab" instead.

Episode 2, Alan needs Charlie to be his receptionist for the day so he can stop Jake getting expelled from school. Charlie with a lot of caffeine in his system when they're in the car tapping a song and making suggestions for how to make money in traffic jams is hilarious.
Episode 5, Alan calls Charlie a misogynist, you think he'd respond with some witty response, instead he grabs a dictionary.
One of Alan's finest would be him naming off movies in a movie trivia game but adding "Blow it out your ass!" during a meltdown of his in "That Special Tug".
Really, the entire episode. Did you forget "There's not enough bowel movements left!"?
Charlie's showing Alan how their mother can make any good thing bad and is later proven right.
Alan states that "I need to communicate after lovemaking. I need to share!" after a chat with his girlfriend Kandi proves to be rather...silly.
Charlie: Well maybe you should've thought of that before you started boinking a girl with the IQ of Tickle Me Elmo.
After Jake mentions about going to his first boy-girl party, Alan and Charlie get into discussion about who should give him advice, where Charlie delivers this quote to his hopeless romantic brother:
Charlie: Face it, Alan. What can you bring to the table other than a lifetime of abject failure with women?
The entire opening scene in "Don't Worry, Speed Racer," but especially:
Alan: Look, Jake, it, it, it— it's not that you have to be particularly smart to have sex.
Berta and Charlie: Yeah, look at your dad!
Not to mention...
Charlie: Really, how much more damage could we have caused?
Charlie offers to take Alan out for dinner and Alan protests about not getting a choice in where they go like Charlie's dates and Charlie decides to troll him by acting like Alan's his date and making lots of innuendo to make Alan shut up.

Charlie: Will you listen to yourself?! Alan: I CAN'T listen to myself. All I hear is aaaaaaaaaaaaaaaaaaaaaaaaaa!! *walks to the piano* C-Sharp! C-Sharp is the sound of approaching deafness!! aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa!!
Charlie's passed out at the table and Jake sees him there, when Berta walks in, she makes the following comment.
Berta: You really shouldn't see him like this, Jake. *whips out a towel and places it over Charlie's face* There! Now you can enjoy your breakfast.
And moments later, when he wakes up with the towel still in place...
Charlie: Oh my God, I'm blind! (Alan removes the towel) It's a miracle!
Why Charlie wants to go to Evelyn's funeral.
Alan: You'll be going to Mom's funeral, won't you?

Alan: Typical. Nothing for Alan to do.
Charlie: OK, you can cut off her head and hold it up for the villagers.
From the episode "I Merely Slept With A Commie", Charlie's Brutal Honesty and Alan's completely deadpan reaction to how they're supposed to convince Evelyn to change her ways so people will actually want to come to her funeral.
Alan [to Judith on the phone]: I'll tell him [Charlie] to keep his hands off Myra. And then, I'll tell the rain not to fall, the earth not to spin, and you to STOP NAGGING ME! [hangs up] Oh, boy, I'm gonna pay for that.
Berta: You know what your problem is? Phone cojones.
Alan: Excuse me?
Berta: When you're on the phone with her, you got boulders between your legs. The minute you hang up, you're as smooth as a Ken doll.
Charlie whilst he's drunk at the start of S04 E22, mostly the inability to unlock the front door.

Alan: I'm not talking to you.
Charlie: Yeah, well, I'm not talking to you either, except for right now, this is me talking to you, but, no longer. [makes pop sound]
