Normally when I see an animal die on film, it always made me sad.
But for the stinger, I vote for when Michael killed the dog.
Because it looked like they were embracing.
And it made me giggle.

Laurie: You know Annie some day you're going to get us all in deep trouble.
Lynda: Totally.

I went with the guitar feedback leap onto the car.  (around 9:58:03)

The sound effect cracked me up.
