Mid 90s were fun at Uni.

Replacing a T-connector with a broken one to sabotage unpopular classes... Or binary searching it with a terminator to save one you liked...

Learning that pinging Windows 3.1 with a big payload would BSOD it and writing a script to perform a rolling BSOD of the entire lab while sitting in the back...

Sending random insults to random spots on ttys while people read their mail using Elm...

Writing a trojan to steal and then delete the MUD accounts of the dudes hogging the only 2 computers with Internet access available to undergrads...

And being caught and let go with a not so stern warning. Simpler times.
