A traveling salesman employs a man with a stutter to sell toothbrushes.
His expectations are low for this guy, so he gives him a couple dozen toothbrushes to sell, expecting him to flop out.
To his surprise, the man returns in an hour with all the money.
"S-s-sold then a-all!" he says.
The salesman chalks it up to beginners' luck, and hands the stuttering man a hundred toothbrushes, and sends him out.
By the end of the day, he returns with all the cash from selling them.
"F-f-finished. I c-c-can sell a lot m-more" he says.
Bewildered, the salesman hands the man box upon box, a thousand toothbrushes, convinced that this will keep him busy for a while. But in 3 days, the stuttering man returns, having sold all the toothbrushes.
"That's it" the salesman exclaims. "How can you sell better than me? You have an obvious stutter, it must be impossible to complete a sale. Show me how you manage to sell so many of my toothbrushes".
So the man with the stutter takes his boss to the airport, where he sets up a table in a busy terminal. He displays the toothbrushes and some chips n' dip on the table. The salesman stared at him, stunned.
"This is it? That's all you do?" "T-t-taste the ch-chips, man".
The salesman walks up and takes a chip, dips it, and eats it. He instantly spits it out and starts gagging.
"This, ---spfftt---, this tastes like *shit*!" "Y-y-yup. Want a t-t-toothbrush?"
