Have not thought of this one in years-but Rapaire's post above brought it to mind.

Old lady goes to the butcher shop for a chicken. Tells the butcher,"bout 4 pounds, nice & plump."He brings one out to her on butcher's paper, she checks it over, no feathers, nice & white, she spreads the legs and puts her nose in the cavity and takes a deep breath to see if it's fresh. The butcher is ticked off & says, "Hey Lady, do you think you could you pass that test?"
