When I was a teenager I was briefly in a couple of detention homes before I went to reform school. They seemed to think I was anorexic around that age because I was shy about eating with people watching me. Because of that in between the two homes they brought me to the emergency room for a check-up.
The funny part is when they asked me "what is the least you have ever weighed?" I said "7 pounds, 1 ounce." Even they thought it was funny.
