As I remember Wham-O made hulu hoops and frisbees. I don't remember these other wacky products. I can just imagine asking my mother to buy me steel tipped darts for my blow gun. So much more fun than spitballs and a straw.
Can you imagine showing up for a sporting event or a golf game wearing this thing? People would think you have some strange handicap.
I remember an umbrella hat from the 70s, which had some special name but I can't remember. I don't remember these from Wham-o though.
Now if I see this on someone's head...and I have that blowgun...no jury in the world would ever convict me. Its like a moth to the flame baby.
