It just so happened my 3 year old did. Neither of us new this at the time though.
We got home at 5 yesterday and he insistently begged to go to the playground. I finally said yes after the 37th time. We were outside for about 30 minutes and after chasing the 15 month old around, I looked up and there it was. So thank you M, for giving me the opportunity to see the light.
I only had the crackberry with me, so I did the best I could.
