Clever Salesman

A well-dressed salesman stopped a man in the street and asked -
'Sir, would you like to buy a bottle of this mouthwash for $200?'

The man said, "Are you nuts? that's robbery!"

The salesman seemed hurt and then tries again -
'Sir, since you are a bit irate, I'll sell it to you at half price - $100?'

Yet again, the man replies frankly – 'You must be crazy pal, now go away!'

The salesman then reaches into his suitcase and take out two cakes and begins eat up on one of them. He tells the annoyed guy -
'Sir, please share one of my cakes since I have irritated you so much'.

Unwrapping the cake, the guy takes a bite; rapidly, the guy spits it out and says:
'Hey,' he snarled, 'this cake tastes like crap!'

'It is,' the salesman responded. 'Wanna buy some mouthwash?'
