LA and NYC's public transit systems got in a Twitter war over baseball playoffs

Now that we know the New York Mets and Los Angeles Dodgers will play each other in the National League Division Series next week, it was only a matter of time before the Twitter boasts and friendly wages between the denizens of their respective cities began to burn up social media.

Hollywood vs. Broadway. Sunshine vs. vibrancy. Bagels vs kale. Traffic vs. traffic. We all know the spiel.

But who expected the first big shots to be fired by a bunch of each city's civil servant workers?

Metro Los Angeles got the smack talking going Wednesday night:

Hey @MTA please tidy up the 7 train, @Dodgers blue is coming to town. #lolmets @Mets

— Metro (@metrolosangeles) September 30, 2015

And the MTA fired back — albeit sort of weakly:

Don’t worry, @MetroLosAngeles – we sweep our subway just like the @Mets will sweep the @Dodgers

— MTA (@MTA) September 30, 2015

LA even found a way to put Twitter pineapples on NYC's No. 1 delicacy — namely The Pizza Rat:

A friendly wager, @MTA? Perhaps your famous New York pizza. #Dodgers #LolMets pic.twitter.com/5g1vpMBuZF

—really touched a sore spot with NYC;

Then LA hit the Mets where it hurts:

.@metrolosangeles Happy to wager on who wins the series. Care to wager on who gets more fans to the ballpark?

Round 1: Los Angeles.
