I've been requested to come up with a little joke, so here goes.

Two sales guys are working for a toothbrush company going door-to-door to sell their brushes. They are each making good money selling 25,000-30,000 per month.
A guy within the company really wants to join the ranks of the sales guys but he has a horrible speech impediment (stuttering and whining at the same time when I reference him talking). He asks the pros " Hhhhooww ddooo III ddooo iittt?" (I'll only do that once, you get the idea). They tell him the lines to use and send him off, door-to-door.
At the end of the next month, they're comparing numbers and realize speech guy only sold 10 brushes. Well, he needs a month to get up and running they figure.
Another month goes by, he only sells 6. Wow, he's not going to make it, they now think.
At the end of third month, they're comparing numbers and realize the guy sold 125,000 brushes. Holy cow, they say. How did you do that. The guys tells them he went to the airport and sold them to people getting on planes. Well this they gotta see.
So, they go out to the airport and sneak up and watch the guy. He has a little booth set up and he's giving away free chips and dip. They move in a little closer to see how he closes the deal, this super sales guy!
This is what they over heard;

Hi, would you like a free chip to dip.

Yes, I would. Hey, that dip tastes like $hit!

Why, thats because it IS pigeon $hit, wanna buy a toothbrush?
