A guy's driving a friend of his around, and he comes up to a red light, and just shoots straight through it.

The guy goes "WHAT THE HELL ARE YOU DOING?!"

The driver says, "Relax, it's fine, I'm just running a red light, my brother does it all the time."

They turn a corner and come to a set of traffic lights. This time they're green. The driver pulls up and stops. The friend goes "What are you doing now? The ligts are green!"

The driver goes "My brother might be coming."
