Also, the act where Clouseau and Maria Gambrelli must enter into a nudist colony, searching for a specific person. The person they are seeking is found dead. In the end they must escape from the colony without their clothes, so as not to be framed, but they end up stuck in traffic, where onlookers discover that they are nude. They both are taken to the police station with three cops "glued" to the back window of the paddy wagon, looking in at them.
Made funnier by the fact that it's the culmination of a Running Gag of Clouseau being arrested and being hauled away in the same paddy wagon for failing to provide "Licenses" for his disguises, with visual gags representing most of the disguises sticking out the back of the wagon.
The entire chase sequence toward the end of the original Pink Panther film.
"Francois... I've just cut off my thumb."
Dreyfus lends himself to a lot of these, mostly out of his immense hatred for Clouseau.
In The Pink Panther Strikes Again, Clouseau jumps off the gym's parallel bars, and falls down the flight of stairs next to them.
Clouseau's interactions with the innkeeper:
Clouseau: Tell me, do you have a ruhm?
Innkeeper: I do not know what a 'ruhm' is.
Clouseau: [laboriously looks up the word 'room' in his German dictionary] Zimmer.
Innkeeper: [cheerfully] Ah, a ruhm!
Clouseau: *sees a dog lying on the floor* Does your dog bite?
*Clouseau reaches down to pet the dog, and is bitten*
Clouseau: I thought you said your dog does not bite!
Innkeeper: That is not my dog.
This dialogue between Clouseau and Dreyfus at the beginning.
Clouseau: I'm afraid this is just not your day, my friend.
Dreyfus: But it is my day. It is, my friend, after three long terrible years, it is at last my day! I will not permit, repeat, not permit anything, repeat, anything to spoil it. Now I will walk you to the gate, and I will kiss you good-bye (kisses Clouseau on both cheeks) and you will drive off in your new car, which should rightfully be mine. And then I will have my interview with the Sanity Commission and they will set me free. And then...(fake arrow hits Dreyfus on the head)(cheerfully) I will kill you! (begins trying to strangle Clouseau and then chases him to his car) KILL YOU!
Clouseau: Francois, start the car! (Francois gets in and starts the car up and drives away)
Dreyfus:(still chasing Clouseau) KILL YOU, KILL YOU! (gains on Clouseau, but an orderly grabs him and stops him) KILL HIM, KILL HIM! But I want to kill him!
To say nothing of Clouseau's interrogation of the staff.
What makes the Clouseau-Dreyfus scene great is that it starts off relatively pleasant, and Dreyfus is trying very hard to remain calm and civil, and even to like Clouseau. Clouseau is, of course, being as amiable as ever, but he constantly tips Dreyfus into the lake and the poor man's sanity gradually deteriorates.
Any Cato vs. Clouseau moment.
From Strikes Again:
Clouseau: you ave a-rrreceived a beamp. You could receive a conceussion from such a beaump.
Clouseau's car being sabotaged, causing him to crash into a swimming pool, then soon after ANOTHER car he is driving is sabotaged, causing him to crash into the same pool while they're towing out the first car.
At the close of Revenge of..., when Clouseau is being shot at by Dreyfus:
Clouseau: It's me!
Dreyfus: I know! (continues shooting)
"Special Delivery, a Beaumb! ("bomb") were you expecting one?"
Curse of... is a dire film on the whole, but The Reveal that Clouseau now looks like and is played by Roger Moore is Actually Pretty Funny thanks to excellent work on the actor's part. He even makes getting an ice bucket stuck on his head work for him! It goes with the suit!
Also, the dream sequence where Dreyfus dives into a pool of Jell-O.
