and maybe there is more than one version of the movie dialog. The way I remember it is like so:

RAY: Everything was fine with our system until the power grid was shut off by dickless here.
WALTER PECK They caused an explosion!
MAYOR: Is this true?
VENKMAN: Yes, it's true. This man has no dick.

Either it was "They caused an explosion", or "These men are con-artists". I remeber the explosion bit.
