I saw the commercial that Yo Yos were invented as a self defense item. I thought this was so funny but it would make a great gag gift for people for Christmas along with some funny directions or a poem for it's use.
I can remember when I was a kid playing with a yo-yo....It hurt when it came back and hit you in the head. The yo-yo's from years ago were a lot heavier than todays.
Growing up I had 1 brother--and with a yo yo he was really dangerous!! His yo yo lit up when you would drop it, really cool until he hit you with it.... :thud: Thank goodness I only have 1 brother!!! Otherwise my sister and I would have been in real trouble!
