The Main Thing Is That It Works

When your code is held together by a cascade of else if statements that somehow manage to keep the entire structure from collapsing. Sure, it's a nightmare to maintain, and any slight change might bring the whole thing crashing down, but hey—it passed QA! This is basically the architectural equivalent of saying "I'll fix it in production" while crossing your fingers behind your back. The building inspector would definitely give this code a 418: I'm a teapot, because this logic shouldn't be serving anything.
