Those big fan balloons

[Walloon]

Is there a proper term for those tall, tube-like balloons that are attached to a high-powered fan on the ground, and are usually in the shape of a person? Conan O'Brien (http://www.nbc.com/Late_Night_with_Conan_O'Brien/video/index.shtml#mea=268396) had one made in his image recently, dancing around willy-nilly at the entrance of Rockefeller Center.

Not to hijack, but those things give the willies, for some reason. Ban 'em, an 'em all, I say.

There's a used car place near me that often puts a couple of them out the front - right by the road -on the approach to a busy and fast-moving roundabout junction. They actually make contact with passing cars when they flop over in the direction of the road.

I guess the owners are trying to get people to smash up their existing cars so they'll need new ones.
