This is an old joke my dad used to tell a lot, but I've seen it on the internet as well. He didn't create it.

So one day I'm driving around with my friend, when the light goes red and I zoom right through it.

"Woah man, what are you doing?" He says.

"Relax man, my brother does it all the time" I say.

So we keep going and encounter another red light, so I speed through it again.

"Seriously, you're going to get us killed!" He says.

"Relax, my brother does it all the time" I say once more.

Then we approach a green light, and I finally stop the car.

"What are you doing?" My friend asks, obviously confused.

So I answer, "Hey, my brother might be coming!"
