Dr. Hax. If he sees you hacking, he will summon a computer monitor to smack you in the face, removing whatever cheat you've been using, from CS hacks to God Mode itself. Repeated throughout the series in various fashions, and almost always a CMOA for himself.
"I can...break these...cuffs!" Taken from an infamous scene from the TV Show Cops, a man tries to break out of his handcuffs. He fails...after bursting into flame and knocking over everyone in a several hundred-yard radius.

Billy Mays pulling off a Houdini and faking his own death.
Dr. Hax going nuts when Billy disappears. This is the man who is able to generate a computer monitor from nowhere and hit you in the face. And he's rendered useless. Though his reaction can be considered awesome as well.
Billy Mays staging a massive operation to ruin Vince Offer's career. With the help of Civil Protection.
"Project Early Retirement Accomplished.Your family is waiting for you outside." This phrase is a CMOA, CMOH, and Tear Jerker all at once. Considering the sorrow that comes with anyone's death, the thought of having that person back again is certainly a happy one, and the chance that it could happen (though in this unfortunate case, it won't) gives the line resonance to this troper at least.
He even manages to give one to a random video response by giving "Oddball Matt" his request to make him "IN 3D FORM", and Matt proceeds to smash a computer ancd cause a gigantic explosion destroying the building around him.
