Pettiest thing you've done during notice period?

I'm currently in my second month of notice and the management here is still expecting me to take ownership of new features. Like bhai I am literally counting days till my exit, why would I care about your Q3 deliverables.

My manager was a massive micromanager before I put down my papers. Now whenever cross functional teams ping me for urgent fixes or KT, I wait exactly half a day to reply and just drop a "Please loop in my manager as he will drive this going forward". I also silently unshared the workspace for some custom scripts I wrote that automated half our weekly reporting. If they want to treat people like cheap labor they can figure out the manual work from scratch.

I know it's a bit evil but it feels amazing to watch them scramble over things they took for granted for years. Ngl I'm enjoying this phase way too much.

Curious to know what kind of petty stuff you guys have pulled off before leaving an org?
