What Shape?

A man went to buy his wife a new bra but had no idea what size she needed. Sales lady tried to help him. She asked, "Is your wife shaped like a grapefruit?" "No, not a grapefruit." "Is she shaped like an orange?" "Um no, not an orange." "Is she shaped like an egg?" Man's face lights up, "Yes, that's it! Like a fried egg!"
