My husband had to explain! 
For the benefit of those not following baseball:
The 6 train goes to Yankee Stadium and the 7 train goes to Citi Field - the Mets home stadium
Juan Soto, a current Yankee, signed a 15-year, $765 million deal with Mets, guaranteeing that he will not be swiping his OMNY Card to ride the subway.
I definitely know more about bands than baseball!

It’s Chef Mimal! Son learned that mnemonic in elementary school and I still use it.
I learned this in elementary school and have since discovered it puts me in the minority among people I interact with. My kids know it (from me) and are always amazed to meet people who cannot locate the Mississippi River (front of the baker).
That’s so cute. I never learned that mnenomic - is there one that includes Ohio and Iowa (which for some reason I can never tell apart.) My MIL was from Iowa, but since her family disowned her and also died before I was around we never visited. I’ve driven across the country three times, but somehow skipped Iowa and Nebraska every time. I’ve driven from St. Louis to Cincinatti to Columbus to Pittsburgh at least. 
We once changed it to French accidentally so I was the only one who understood it. So funny.
