I work in IT and frequent different school systems within my state. On Fridays I'll usually wear funny technology related shirts. I was once in a high school and had a shirt with a cassette tape, a floppy disk, and a VCR tape on it. It says something like "never forget" below the images. A high schooler pointed to the floppy disk on my shirt and said "hey, I know what that one is, you have the 'save button' on your shirt".
