15. Pedialyte
If there's alcohol, you can bet at the back of the fridge you can find bottles of pedialyte. We make sure we go to Walmart early in the morning and buy 2 or 3 bottles each. We all make sure our names or initials are on the caps to make everyone know the bottles are claimed. So on Christmas Day when we're recovering from our hangovers, we all have our pedialyte to help us recover.
