My grandfather was from Sweden, and some English words were hard for him to understand. So he called skim milk "skinny milk." When I was younger I thought that "skinny milk" would make you lose weight (I was a pudgy child) so I once drank nearly a half gallon and was disappointed the next day to find out that I had not lost any weight!
