By Leo Black<br /><br />A sneaky lab mouse avoided capture by climbing on a lab-tech's shoulder - in a scene straight out of Tom and Jerry.<br /><br />The lab worker had taken the rodents out of the cages to weigh them when three of them jumped out and escaped.<br /><br />A video from the lab in Shanghai, China, shows technician Tian Yongyi frantically searching for the mouse as it sits on her back, waving its tail.<br /><br />She can even be seen lying on the floor to look under cabinets as the smug rodent sits on her back.<br /><br />The white mouse managed to avoid capture for more than 10 minutes after the lab tech eventually realised the mouse was sitting on her shoulder.<br /><br />
