I grew a useless beard once. It just laid there, doing nothing. It didn't get a job, do chores, or give massages.
Sure, it would catch food, but it rarely ever gave any of it back. When I'd talk to someone, I could see from their expression that they were staring at my beard. Clearly, it was mocking me. Birds wouldn't nest in it, but I did find a couple of bears hibernating for the winter in there. I tried to charge rent, but my beard helped them sneak out the back.
When my beard grew long enough, I tried to comb it over, but it felt scratchy on my eyes. I parted it in the middle, pulled each side up, and tied it in a bow on the top. Oddly enough, that didn't look as cool as you might think it would.
In the end, I shaved it off. Everyone's happier that way. Sure, I get angry looks from bears, the sun's reflection off of my head can overload solar panels, and a significant amount of food gets entangled in moob hair. In general, though, it's worked out pretty well. I got a postcard from my beard recently from Gnu Zealand. Apparently, it's earning a large bag of gold working in Hobbit movies.
Sure. Now, it gets a job...
