Every time Sawyer uses an insult with the word "pig" in it, such as calling her workspace a "pigsty" or calling Danny "pigheaded," there just happens to be a pig standing nearby, causing Sawyer to turn to him and say "No offense." and the pig replies "None taken." Adding to the hilarity is that it's a different pig both times!
Every time Darla can just barely keep up her fake smile, especially during the tea scene with Danny. She gets right up in Danny's face in an attempt to get him to take her offer of "help," and she starts to slightly twitch psychotically and her eyes briefly turn red before Danny says anything.
Also, her utterly amazing Villainous Breakdown when Danny upstages her at the premiere, complete with eye bulging and panicked laughter as she desperately tries to defuse the situation.
Max during the first rendition of "Big and Loud". "Get hot, Ms. Dimple."
After Sawyer's beautiful jazz song, Tilly swoons in admiration...and knocks the diner behind her off its foundation. (From inside, a collective, startled "Whoa!") Then she yanks the building back into place. (Another, briefer "Whoa!")
When Sawyer hears the alley jam going on, she investigates from the fire escape ladder... Which then slowly comes loose, and takes her down with it to street level with a resounding crash, causing her to jump back, arched forward on all fours with fur on end like a shocked cat would, and sit there stunned for a second before glancing to see if anyone saw that, before dusting herself off and getting composed.
Before the Dance-Off, Danny gets a good Deadpan Snarker moment. Bonus points for sliding across the floor with his tail while lounging and saying said remark. Also Sawyer’s shocked response chefs kiss .
Danny: Not bad. A little rusty, but hey, who's perfect?
This exchange where Danny suggests getting everyone an audition with LB Mammoth:
Danny: I'm sure he'd love to see some real talent!
(Darla, who is spying on them, growls with rage and ends up baking, then shattering her mud mask)
Cranston, while watching a particularly diabetes-inducing scene in "'Lil Ark Angel":
Cranston: Shoot me.
To overemphasize Max as The Stoic, up until the very end of the movie he never moves his jaw when he talks, and just delivers all his lines through clenched teeth. It gets increasingly funny as the film goes on, especially when he's not delivering intimidating lines.
The absurdly long note at the end of "Nothing's Gonna Stop Us Now." It starts inside the theater, then we cut to outside, where the split-second of silence is broken by the roof literally getting blown off.
As pointed out by The Nostalgia Critic, every time the studio makes a movie, Woolie has to be put in make up, squeeze his head through the logo and do the sound effect.
Max's Evil Laugh as he closes in to finish off Danny, only to find the Darla balloon below him ready to pop; made doubly funny as up until this point he had been The Stoic; his epic Oh, Crap! reaction when Danny sends him rocketing away is simply priceless.
Danny: Very good! [pops balloon, sending Max rocketing into space]
Becomes a Brick Joke later when we see after the show and Darla's literal downfall that he's still floating about on the balloon.....In Paris!
During the standing ovation for "Nothing's Gonna Stop Us Now," a random audience member's teeth come breaking off like a Soft Glass pane.
A funny detail of the "Where Are They Now?" Epilogue is that after getting recognized, the animal who had the best career was Cranston, who got 5 movies compared to the others getting only 2 or three.
