You know that moment when your database query takes 47 seconds to run and you're sitting there like "surely this is fine"? Then reality hits and you're frantically slapping EXPLAIN on that bad boy to figure out which table scan is eating your lunch. Turns out joining 6 tables without indexes while doing a substring match on a million rows wasn't your brightest idea. Who would've thought? Now you're in full detective mode, adding indexes like they're going out of style and rewriting that monstrosity you called a query. The real kicker? After all that optimization, you realize you could've just cached the result. Classic.
