I’m not sure if this has been posted or not, I didn’t see it.
This past Sunday on CBS Sunday Morning (one of the best programs on TV) they did a short segment on Dr. John (Lucky) Meisenheimer and his yo-yo collection. Enjoy.

Wow! Crazy big collection.
If I’m not mistaken, he has a large barbecue at his house every year at the Worlds. I believe it is scheduled for this year as well…but I’m afraid I won’t be able to make it. Only a doctor or an attorney could afford that kind of in-house museum. 
And a very understanding wife.
