In college 20 years ago some student hit "reply all" on some random email to complain about something and thus started a 2 day long chain of emails of people arguing with the person and others yelling at everyone for hitting "reply all" And so thought it was a good idea to reply with a link that said something like "go here to make the emails stop" which was just my picture making a stupid face and some javascript I made that would open 2 more identical windows, then those 2 would execute until something crashed. It was amazing I didn't get in trouble for it and some guy at the 7-11 recognized me. Highlight of my life.
