On Saturday, a lady came into the shop with an oboe. "I'd like to see Mr Ovary about my Oboe" . Mr Ivory was produced to see to the oboe, the lady apologising for getting his name wrong.
A little work was needed on the instrument, so the lady arranged to come back during the afternoon.
She returned after some hours, and said " I've come to see Mr Ivory - he's mending my Ovary"
Well, he's a very clever man, but he doesn't mend those!
