Three tough biker dudes...

...walk into a bar. They notice a skinny, bespectacled little guy sitting in the corner by himself, and decide to have some fun.

They order three beers, and one of the bikers says, "Charge these to that little runt over there in the corner." Then he calls over to the little guy, "Hey, Poindexter, you don't mind paying for our beers, do you?"

"Um, no," says the guy meekly. "I guess not."

Then another biker says, "I could use a smoke. I'm fresh out of cigarettes, though. Hey, Four-Eyes, go over to that vending machine and get me a pack of Winstons. I'm out of cash, so you'll have to pay."

The little guy obediently buys a pack of Winstons and brings them to the biker.

"You know," says the third biker. "My boots are mighty dusty after riding all day. Why don't you take that rag off the bar and give them a good cleaning? In fact, give all of us a shine."

The little guy takes the rag, drops to his knees, and shines their boots while they all snicker at him.

When he's done, he quietly asks, "Can I go now?"

"Yeah, I guess you can go. Beat it, Runt."

He quickly scuttles out the door while they have a good laugh at his wimpiness.

A few minutes later another customer walks into the bar. "Hey, who was that little guy who just left?"

"Just some spineless wimp. Why?"

"Well, not only is he a spineless wimp, he's also the worst driver I've ever seen. He just ran over three motorcycles in the parking lot."
