I’ve spent a good chunk of my morning scouring the Internet, and from what I can tell, this did not happen.

I’m not sure what the source of this information is–though I might guess at a couple of disgruntled fans who have an axe to grind with Rick’s writing and have already shown that they’re not above distorting the truth or outright lying in order to try to get him fired–but this does not appear to be legitimate.

Where did you hear about this, might I ask?
