Something's rotten in NYC

Yesterday's big smell in NYC is still a mystery. There is finger pointing all over the place as is normal when mysterious smells come around with each person pointing his finger at the other. I say his because we all know that women do not participate in big smells.

I have the sure means by which the source of the smell can be identified. In fact, any third-grade boy knows the solution:

First smeller is the feller

It's that simple.
