One afternoon, this guy drives down a highway to visit a nearby lake and relax.  On his way to the lake, a guy dressed from head to toe in red standing on the side of the highway gestures for him to stop.

The first guy rolls down the window and says, "How can I help you?"

"I am the red goober of the highway.  You got something to eat?"

With a smile in his face, the first guy hands a sandwich to the guy in red and drives away.  Not even five minutes later, he comes across another guy.  This guy is dressed fully in yellow, standing on the side and waving for him to stop.

A bit irritated, our guy stops, cranks down the window, and says, "What can I do for you?"

"I am the yellow goober of the highway.  You got something to drink?"

Hardly managing to smile this time, he hands the guy a can of Coke and stomps on the pedal and takes off again.  In order to make it to the lakeside before sunset, he decides to go faster and not to stop no matter what.

To his frustration, he sees another guy on the side of the road, this one dressed in blue and signalling for him to stop.  Reluctantly, our guy decides to stop one last time, rolls down his window, and yells, "Let me guess.  You're the blue goober of the highway, and just what on earth do you wanna have?"

"Driver's license and registration, please."
