You may remember Thaddeus Plotz as the CEO of Warner Brothers Studios on Animaniacs. His first and worst offense was keeping the Warner Brothers (yes, yes, and sister) locked up in the water tower all those many years. His anger-ridden outbursts and short temper, as well as his conniving business savvy is what keeps the Warners on his case, like constantly. My favorite Plotz moment? The episode where he sent a clown (Jerry Lewis, anyone?) up to the water tower to wish Yakko a happy birthday. We find out that it is not just a friendly gesture, it is a calculated move by a savage clown-hater, sending the innocent yet annoying entertainer to his doom. If that ain't ruthless then I don't know what is!
