My coworker told me he was going to start bringing his pet parrot to work.

This joke tickles our funny bone by playing with the delightful absurdity of introducing a pet parrot into the typically mundane world of an office. Our expectations are set for chaos, squawking, or at least a significant distraction, yet the humor pivots on the coworker's completely deadpan, and utterly misguided, justification. It's an ironic twist where something that would usually be a hindrance is presented as a helpful, albeit feathery, asset.

The core of the humor lies in the literal interpretation of a parrot's most famous trait: mimicry. While parrots are indeed known for repeating sounds and phrases, the idea that this would translate into a productive "second me" for office tasks is where the joke truly takes flight. It plays on the common, perhaps subconscious, desire for an assistant or someone to simply agree with you, twisting it into a ridiculous scenario involving an avian echo chamber. The final touch of "more feathers" perfectly grounds the fantasy in the reality of the bird, adding a simple, visual punch to the already silly premise.
