What was the cause of the Natural Gas Smell and evacutation in Manhattan?

Question

I have it on good account that the whole thing came about from a luncheon visit by Rosie O'Donald and Nancy Grace.
Having had too good a lunch, one let one go, and the other simply reacted with the same. I understand Bill O'Reilly was part of the Pharting Factor.
The cloud of gas was monstrous, and was, indeed, enough to vacate Manhattan.
Thank God Hillary wasn't there, or the gas could have been toxic.

Answer 1

Yes what you just said. I had only heard in the media that the cause was unknown but your answer is likely.

Answer 2

If your theory is confirmed I would like to send my ex-wife there to paint it blue.

Answer 3

the mayor passed gas.
