Nothing says "professional software engineering" quite like bolting a modern extension onto a medieval castle. That's exactly what we do with legacy code every day.
Those blue modern additions clinging desperately to ancient stone walls perfectly capture the "it works, don't touch it" mentality we've all encountered. Ten years of undocumented spaghetti code written by developers who've long since left the company, and management wants you to "just add one small feature" without breaking anything.
Sure, a complete rebuild would be ideal, but who has time for that? So we slap on our modern architectural patterns and hope the whole thing doesn't come crashing down during the next deployment. And hey, at least we're not the ones who built the castle!
