99% stupid. I know of 1 situation where I would like to have it. There is an area I hunt that has a lot of wheat fields, once the wheat gets tall all you can see of the birds are their heads and that tall headed, stupid looking decoy might just work.
Other than that, it is on par with the dirty b, squealing hen, acorn kruncher, butt out and the pump action yelper that used diaphragm calls without the tape!
