A childhood belief about general

when i was a little kid my mom tried everything to get me to eat egg salad sandwiches. she finally decided to tell me that only older people liked them, and that they were often called "high-school sandwiches" because of their raging popularity among the hig-school kids. needless to say, i was convinced, and eventually grew to love the high-school sandwich. unfortunately, i was quite embarrassed when was informed (in my 20's no less) that the name was merely a ploy used by my mom to get a gullible young boy to eat his food. i was still using the term at the time of my disturbing discovery.
