After seeing this video I was reminded of a trip I once made to the Marina Del Rey Costco with my girlfriend.
We were pushing a shopping cart back to the car, and I had asked her if she had ever "ridden" a cart as a kid. She had, but I made her get on the cart anyhow.
She stood in front of me as I pushed, and I told her to lean back on my chest for support. I got her to close her eyes and put her arms out, and then had her open them.
"I'm king of the world!"
She later informed me of how stupid and childish that was, but the point is the same as that mall magician video. There's a lot of fun to be had just by being a little creative and seeing what's available around you.
Stupid laughs make endearing memories.
