Why did the Xbox player cross the road? To render in the buildings.
The Xbox Player and the Road
Explanation
This is a pun that plays on the term 'render' in video game graphics. In gaming, 'rendering' refers to the process where the computer takes game data and turns it into an image, typically the virtual environment including the buildings. The joke implies the Xbox player is going somewhere to render the building, or make them appear.

Well, he can't render the twin towers after those damn iraqis destroyed them.
