I work with a lady who puts everything in her mouth. If she's holding a pen and needs both hands, she puts the pen in her mouth. If she's filing papers, she holds the papers in her mouth while she files. Everything in the office is covered with her germs. She is ALWAYS sick and passes her germs around. When she leaves the office, we "hose down" the office and clean every surface we can. I guess we could staple her lips together...
