What you need is some good ol´fluffin!
We have the worst epidemic of gastroenteritis I have experienced the last ten years among the little toddlers here. The pediatric ER and all the wards are filled with kids throwing up.
I have, however, the perfect recipe for not catching the bugs. It is called 'Gammel Dansk' and is a traditional Danish hard liquor. Guaranteed to drive all the bugs away.
