Hmm...so much inspiration to draw from:
Cromwell: "You have sat too long for any good you have been doing."
Gandalf: "I'd rather stand alone than join you."
And, with apologies to David Allen Coe and Johnny Paycheck (I'm surprise how little of the original lyrics need changing for it to work):
Take this Game and Shove It
For now 15 years
All this time I watched my woman
Trying to seduce every damn troll
And I've seen a lot of good characters die
That had too much XP to throw away
I'd burn my campaign notes today
If I had the guts to say
Take this game and shove it
I ain't playing here no more
My woman done left
And she was the one I built this campaign for
You better not try to stand in my way
As I'm a-walking out the door
Take this game and shove it, I ain't playing here no more
Well, the rules lawyer's a regular bore
The power gamer is a fool
He just bought another sourcebook
Lord, he thinks he's cool
One of these days, I'm gonna blow my top
And that munchkin, he's gonna pay
Lord, I can't wait to see their faces
When I get the nerve to say
Take this game and shove it
I ain't playing here no more
My woman done left
And she was the one I built this campaign for
You better not try to stand in my way
As I'm a-walking out the door
Take this game and shove it, I ain't playing here no more
Take this game and shove it
