Well,  Girl Potato and Boy Potato had eyes for each other, and finally they got married, and had a little sweet potato, which they called Yam.

Of  course, they wanted the best for Yam.
 
When it was time, they told her about the facts of life.
 
They warned her about going out and getting half-baked, so she wouldn't get accidentally mashed, and get a bad name for herself like 'Hot Potato,' and end up with a bunch of Tater Tots.

Yam said not to worry, no Spud would get her into the sack and make a  rotten potato out of her!

But on the other hand she wouldn't stay home and become a Couch Potato  either.
 
She would get plenty of exercise so as not to be skinny like her Shoestring cousins.
 
When she went off to Europe, Mr and Mrs. Potato told Yam to watch out for the hard-boiled guys from  Ireland, and  the greasy guys from France called the French  Fries, and when she went out west, to watch out for the Indians so she wouldn't get scalloped.
 
Yam said she would stay on the straight and narrow and wouldn't associate  with those high class Yukon Golds, or the ones from the  other side of the tracks who advertise their trade on all the trucks  that say, 'Frito Lay.'
 
Mr. and Mrs. Potato sent Yam to Idaho P.U. (that's Potato  University ) so  that when she graduated she'd really be in the  Chips.
 
But in spite of all they did for her, one-day Yam came home and announced she was going to marry Tom Brokaw.
 
Tom  Brokaw!
 
Mr. and Mrs. Potato were very upset.
 
They  told Yam she couldn't possibly marry Tom Brokaw because he's  just......
 
Are  you ready for this?
