We used to rick roll teachers by pretending to copy paste from the internet by writing "Please click here for more information" somewhere in the text.

I haven't thought about that in about 15 years and just started laughing to myself about the time my English teacher was struggling to turn the volume off during study hall as Rick Astley sang almost the entire song at full volume.

In the 90s, I remember there being a piece of student work pinned to the public display board (this only happened to the best work). It had blue links in it. Either the teacher who marked and choose it had no clue what that meant or had no fucks to give, not sure which.
