[Rushmore]

In Blue Velvet, when Sandy's boyfriend catches up to Jeffrey and Sandy right in front of Sandy's house, and they're arguing, and there might be a fight, and it's a little gooofy for just that moment, but...

...then it's all salvaged by the very slow appearance of a naked Isabella Rosselini in the background, with her arms hanging out like she's on a cross, stumbling toward the fracas, bruises and cuts all over her aged, saggy body...

...and the douchebag jock says, "What? Is that your mom?,"
...

...and his douchebag jocko friend says, "Hey. I thought you were gonna kick his ass!"

You had to be there.
