New Model Bathroom Scale

The bathroom scale manufacturer was very proud of the new model being introduced
at the trade fair. “Listen to these features it's calibrated to one-one-hundredth of a pound; it can measure your height as well, in feet or meters; it gives you a readout via an LED or human-voice simulator; and that's not all...”

“Very impressive,” interrupted a none-too-slender sales rep for a chain of home furnishings stores, “but before I place an order I'll have to try it out.”

“Be my guest,” said the manufacturer graciously.

No sooner had the sales rep taken his place on the scale than a loud, very human-sounding voice issued forth, “One at a time, please, one at a time!”
