Cameron introducing Lily to the family, a la The Lion King with 'The Circle of Life' blasting (right after Mitchell has argued with his father's referring to Cam as "overdramatic").
The Funny Back Ground Event of Cam rushing towards the car holding a trash can to break a window (Lily having been locked inside) as Mitchell is calling Onstar to unlock the car. All the funnier when the Onstar woman tells Mitchell to calm his wife down, only for Mitchell to tell her "that's a man."

The whole intercutting of the ADHD discussion between Alex and Claire and Phil's actions in the garage.

"It's a dog and a butler!"
Cam turning to Mitchell and saying, "Wow. You just made figure skating sound even gayer." From a straight character, it'd be perhaps a little off-color. Coming from Cam who has N-Word Privileges, it works.

From "Express Christmas
Claire: Oh, thank God, here comes Phil with the butterball!
The Little Fizbo bit in the episode "Send Out the Clowns". Be prepared to not breath for a bit, it's that gut-bustingly funny.
Cam's zombie-like interview after having to stay up all night consoling Lily on losing one of her toys.
From the Disneyland episode, the whole "Lily on a leash" arc—first Lily barking, then Jay ordering her to heel, then Lily getting tangled up with another leash kid (named Rex!), then Lily running after Chip and Dale (Cam: "And now she's chasing squirrels."

She still won despite freezing onstage doing the routine ("Imagine this at 18!") but she was humiliated and vowed never to perform again but Luke convinces her to do it for the family. ("I know how to push buttons to get what I want. And what I want is a puppet show.") Gloria is a pretty terrible ventriloquist with her mouth clearly moving when "Uncle Grumpy" talks but it's the jokes are funny in a corny way and it's still charming. Then Jay comes out dressed in the same color clothes as Grumpy and complaining about something Claire realizes "Oh my god, she married her puppet!"
While trick-or-treating, Manny is tempted to go with Durkas, the school cool kid. Luke tries to push him into it, while his other friend Reuben argues the opposite. The dialogue in the scene comes off as a bit contrived until you realize that Luke's dressed as Satan and Reuben's an Angels player.

In their front yard, Mitch and Cam finally confront each other about the fact that they ought to be planning their wedding together rather than having Cam make the arrangements by himself. Just as they've admitted the need for Mitch to help reign in Cam's tendency to let things get crazy out of control, this happens - It Makes Sense in Context to the viewer, but bear in mind that from Mitchell's point of view it comes out of nowhere:
A bagpiper, in full kilt and regalia, bursts out of the front door.
