The thread about scenes that stick brought one back that I had forgotten. Thinking back on the Naked Gun movies, there was a scene where Leslie Nielsen's character was questioning someone in a sex shop. Those two were the main focus in the scene while in the background George Kennedy's character was messing around with some of the merchandise. One of the items he picked up looked like a chainsaw with a dildo attached to it. He proceeded to fire it up into an oscillating fury.

Back then, I thought that scene was funny because of how ludicrous and unrealistic it was. Today, I've seen porn in which a dildo attached to a sawzall is used on someone. The age of innocence is over, my friend.

The one that immediately springs to mind for me is when Woody Allen is fighting the giant blob of pudding in Sleeper.

The scene starts at 07:47:

The scene in GoldenEye that takes place in Q Labs is hysterical.

You guys have seen Shaun of the Dead, right? There's that tracking shot of Shaun walking to his store the morning of the zombie apocalypse where there's all sorts of shit in the background. And it's all throughout the movie. I love it.
