Make your own out of PVC rollers. They had a really big one at Dewberry Farm near Katy. Gives your butt a tickle like nothing you've ever experienced.
This is a pic from their website:
"The budget should be balanced, the Treasury should be refilled, public debt should be reduced, the arrogance of officialdom should be tempered and controlled, and the assistance to foreign lands should be curtailed lest Rome become bankrupt. People must again learn to work, instead of living on public assistance."
-Marcus Tullius Cicero, 63 BC
