Beware the leaders of plumbers. Okay, I don't really mean that. This is why generalizing is bad, because certainly there was only one plumber who helped people break into the Democratic National Headquarters offices in the Watergate facility. And really, they were just using "plumber" as a metaphor. None of these guys knew how to fix or lay pipe.
So I'm talking about G. Gordon Liddy, the main plumber behind the Watergate break-in.
The Gate that begat all the other gates to follow, except Bill.
