There is one snake I would definately use for a bag.One of my old bosses,he was such a nasty vertically challenged little b*****d,the tricks he used to pull on some of the staff were so low and he was always devious enough to word it in such a way you would look a fool for challenging him. I'd even skin him alive the nasty little viper.In fact he was so low he'd make a snake look like it was on stilts.
