I didn't know I was playing church league softball

A way of saying you were given a drink so weak it might as well be a punishment from God.

I told my friend, 'I didn't know I was playing church league softball' after I drank that beer.

My mom said, 'I didn't know I was playing church league softball' after I gave her my old beer.

At work, I said, 'I didn't know I was playing church league softball' when I drank the beer they gave me.
