I saw them in Singapore before they went viral, I wish I had grabbed a box and milked that fad. I wonder when the YoYo will roll back in to popularity again.

About three years ago. Every kid that exists in my area had to have a butterfly yoyo. Some convinced their parents to spend hundreds on trick yoyo's. That fad died after about 10 months, though.
