A door-to-door vacuum cleaner salesman manages to bull his way into a woman's home in a rural area. "This machine is the best ever" he exclaims, whilst pouring a bag of dirt over the lounge floor. The woman says she's really worried it may not all come off, so the salesman says, "If this machine doesn't remove all the dust completely, I'll lick it off myself." "Do you want ketchup on it?" she says, "we're not connected for electricity yet!"
