A potato King calls his three potato daughters in to see him, and he tells them that they are to "fly the nest" and go in search of husbands. They should bring their selected partner back for the King to give his blessing before they tie the know. So, off they go...
A couple of months down the line, the eldest daughter returns. She brings with her a Jersey Royal potato. The King is pleased. The potato comes from a respectable family, one he would love to see his daughter wed into, and so gives her and the Jersey Royal his blessing.
Three more months pass, and his 2nd daughter returns from her search for a man. The King is anxious to see who she has chosen. She presents to him a King Edward potato. The King is ecstatic; the King Edward family is the most highly respected of potato families. He gives them his blessing.
Nearly a year goes by and his youngest (and favourite) daughter has not yet returned. He starts to worry, but is relieved to see her turn up. He wonders how on earch she could top the "finds" made be his other two daughters.
"Dad, look! I've found the perfect husband!" she says.
She presents to the King, Des Lynam. The King falls the floor in dismay, shaking his head.
"NO, I forbid you to marry him!" exclaims the King.
"But why??" questions his daughter.
"He is a common-tata!"
