⚠️ Disclaimer: The following jokes have been clinically tested and proven to cause: involuntary groaning, eye-rolling at dangerous velocities, and the sudden urge to explain the punchline to non-technical people who will not find it funny. Side effects may include losing friends who don’t get the reference. Havoc accepts no responsibility for broken relationships caused by pun exposure.

“It was default credentials. The username was ‘admin’. The password was ‘admin’.”
“The phishing simulation had a 94% click rate. The CEO clicked twice.”
