Reddit reviews Invisible Dog Leash - Great Gag!

Simple

Do you have a dog? Take him/her for a daily walk.

If you don't have a dog, you can pick up one of these for like $6 and do it anyway.

I think I was 4 the first time I went to Disney World, and I saw some kids walk by with novelty invisible-dog leashes, and so after that, I thought they really had invisible dogs at Disney World.

I see where you are going there, but the toy is often referred to as an Invisible Dog Leash.

I was thinking about this, and I think it'd work easier to use http://www.amazon.com/Invisible-Dog-Leash-Great-Gag/dp/B0006GK8GE instead of balloons. Then use foam to create the outline of the children.

I see a couple of people with one of these, yeah? I had one like that when I was a kid!
