Another Pic: "RODEO BOY??"

OK OK... I could not believe my eyes when I saw this at my friends house. Its called "Rodeo Boy" and seems to be an excersie machine that simulates riding a horse. I died laughing when I saw this. The name alone was funny...

So I told my other American work colleagues about it when I arrived in Tsukuba. They could not believe me so we went to Kojima and found it. Everyone was surprised to see it. We all got our pictures with it. I think the thing that everyone laughed at was the name "Rodeo Boy". It is an interesting machine. But we would never ever find it here in the United States. So my question is this..... Has anyone had success using this???
Hang in there Cowboys and Cowgirls!!!!
