As my daughter Em would say, "Whon Whon. " My husband taught her this sound effect for when things go wrong. It is actually very hysterical when something really does go wrong and my husband and I are tense (usually involving directions.) All of a sudden we will hear "Whon Whon" from the back seat. You can't help but laugh.
Back to the corn, "Whon Whon!" They shriveled up! I did see that you can buy nice flat husks at the craft store or use tamale wrappers. So much for being resourceful -- off to the craft store we go!
