G.U.N. Truck 

A heartless, automative beast developed by the Guardian Units of Nations, or G.U.N., military branch. It is commonly found recklessly wreaking ungodly havok upon the sloped streets of San Francisco. It careens through the streets going on a relentless killing spree, destroying millions in public property in the process. It is three-stories-tall, two-lanes-wide, and is capable of making impossible 90 degree turns at inconceivable speeds.

It's sole purpose is to chase down and deflate the world-famous Sonic the Hedgehog, who was wrongly accused of museum theft commited by a similar, but unrelated, hedgehog at the time.

The G.U.N. Truck would eventually crash into an inconvenient bridge and begin it's redevelopment process. After economic woes and an intense room in court, the G.U.N. Federation rebuilt the same truck that got themselves in trouble in the first place with fancy new features like bussaw arms and rockets that allow sideways driving alongside buildings.

Guy 1: "Why the hell would it do that?"

Guy 2: "It was trying to flatten a woodland creature."

Guy 1:"..."

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
