Nothing crazy, but something I always laugh at.
I was so excited to meet a legit/professional dev team the first day of my career.
I was paired with a Sr dev and sat in his cubicle so he could show me some backend update to a prod app with 20K internal users... "normally I'd run this on the dev server, but, its quick & easy so Ill just do it on prod"
...watched him crash the whole thing & struggle the rest of the day to try and bring it up. I just sat there in awe, especially as everyone came running over and the emails poured in, while the Sr Dev casually brushed it all aside. He was more interested in explaining how the mobile game Ingress worked.
