This is Officially Not a Trivia Contest (though it's certainly trivial so maybe close to that!)
I'm not very good with math -- I ignore it more than 60 percent, or almost half the time! So I'm not sure what made me think of this, but I found myself wondering ...
What is the maximum number of hits a pitcher can allow in one inning without giving up a run? I'm sure there must be a "right" answer to this; it's not an "infinity" question like it would be if we added the word "unearned" to the question. So here we go -- check my work, grade my effort, let me know if there is another answer, and post your own favorite "thought experiment" question here.
