That was funny stuff !
A customer pulled his car into the repair shop, and asked if we could change the air in car tires ... doesn't the air get stale, and you have to drain it out, and put new fresher, bouncier air in the tires ?
Woman: Do you have one of those: tire pressure, pumper upper, checker thingies ? (tire gauge).
Customer at Home Depot: I have a 220 volt air conditioner, do you have one of those little gray plugs, that step up the wall outlet 110 voltage, to 220 volts ? (an electrician)
