Years ago I worked with a guy who kept the legs of a mannequin dressed in dirty jeans and work boots in his trunk.....
On more than a few paving jobs the legs trick was used ....the legs were placed in front of a roller and the guys frantically yelled at the operator to stop.. Usually laughs were had by all ..Until one operator got so upset and pissed he got into a fistfight with the guy who owned the legs....
