Debugging
When a colleague announces they're leaving, there are two types of developers: those who mourn the loss of institutional knowledge, and those who've seen Billy's SQL queries.
Poor Billy committed the cardinal database sin: using a cross join with a group-by clause. That's like using a flamethrower to light birthday candles – technically it works, but the collateral damage is... extensive.
The remaining team members aren't celebrating Billy's departure – they're planning his execution before he can push that monstrosity to production. Because nothing says "farewell party" like debugging someone's queries that would bring a database server to its knees.
