These are those tired old worn out bags that have worked the same lame ass factory job for 30 years or more and haven't advanced their knowledge since the first week. They are jealous of anyone who took the time to educate themselves and are vicious and anal. It is fun to make them squirm by waliking around with tape measures and talking in scientific or engineering terms.
"Boy, wouldn't it be nice if those scornful farm wives would retire once and for all? They haven't done anything except share recipes all goddamned day."
