Define It Came From The Corner Meaning

It Came From The Corner
Phrase used at the workplace to explain why a particularly stupid, out of scope, or dubious change must be made to a project, because it was handed down by a higher level manager with little understanding of the repercussions. Refers to the corner offices that most clueless managers tend to have.

Worker: You do realize that we've been working on this for 3 months, building it out as it was planned, and now you're asking us to completely change it? We've gone from 90% done to 10% done in 60 seconds.

Middle Manager: Hey, what can I tell you? It came from the corner.
