No, really. It is early on Saturday morning as I am watching the BoSox about to beat the Angels. I can handle it. You can nitpick the OP all you want to. You may decide to nitpick a later post. Go ahead, I can take it.
If this has been done before, I couldn’t find it on search, but I didn’t look very hard.

I thought nothing could be more boring than baseball.
Now I know better.
A nonspecific thread about baseball has proven me wrong.
Just a minor nitpick, but this thread is not about baseball. It is about whatever the nitpick is about.
Get it

That was a great homer to end the game.
BoSox? I believe the name of the team is actually the Boston Red Sox.
Actually SSG Schwartz, you’re wrong. Germany and Japan were part of the Axis, and not the Allies, in WWII.
Nitpick: you didn’t stipulate that we couldn’t lie.
Nitpick: You should have looked harder.
That’s pretty tacky for you to make the first nitpick!
The bravado is a bit much. How do you know you can really take it?
Not to nitpick or anything, but you’ve misplaced your modifier – that should be “you really can take it.”
Not to disagree pointlessly or anything, but maybe you shouldn’t assume that I was not in fact attemtping to distinguish betwixt the ‘real’ world and some other variant.
Misplacing a modifier is as horrible as losing a lagomorph.
I’m sorry, I just have to disagree with you there. Misplacing a modifier is considerably less horrible than losing a lagomorph. I still miss mine. 
I figured this thread would be more specific and to the point.
Technically, your lagomorph has not been lost. Mr Floppy’s current location is known and can be verified if you wish to go out into the backyard with a shovel.
He’s in the military, of course he can take it.
Now then where did I put that soup-in-a-basket meal
You better get the shovel.
Nitpick: It should be “you had better get the shovel” in written English. And a cite even.
(So who’s going to nitpick “cite” or the sentence fragment?)
Nitpick: The “then” part of your statement does not logically follow the “if” part. Your assertion is, IF this has been done, THEN I could not find it. In fact, even if this has not been done, you still could not find it. All possible states of the IF condition give the same THEN condition. Your IF clause is therefore redundant. 
My favorite nitpick in real life goes like this:
Unsuspecting Pal: “I’m going to the bar tonight, if you want to join me.”
Me: “If I don’t want to join you, are you still going?”
UP: “Dick.”
This thread title isn’t in title format.
It should be, “Nitpick This Thread.”
Then it just goes downhill from there.

Not to nitpick or anything, but I didn’t say you could stray from the truth either.
