This is along the lines of Lettermans' 'Great Moments in Presidential Speeches'
Rainjack accusing someone of making an ad hominem argument.
Every time Rainjack is called a cocksucker or something similar, he responds 'you are projecting your sexuality on me', fully unaware that he questions people's sexuality on a regular basis.
Anyone got any others? By the way, I am fully aware this appears near the 'Civility' thread.
