Yanky Gross got a job as a mouthwash salesman as soon as he had to support his wife, and during his first week on the job, he managed to sell 5000 bottles of mouthwash, a major sales record.
His boss asked him: Yanky, how did you do it?
He explained as follows: “Well, you see, it is very simple. I stood out on 13th Ave and 50th St at Mincha time with a container of month old chopped liver and asked everyone if they wanted a free sample. When just about everyone tasted it they told me it tastes like it’s at least a month old – FEH!” So I would tell them – FEH! It is mamash a month old, you know and it was sitting outside all this time – so maybe you want a bottle of mouthwash for a dollar you should wash out your mouth and not get sick!!!”
