Jarbaby’s thread about some guy scratching his nuts on the bus was titled something to the effect of “You, Sir, with the balls”.
Hey, I got a shout!
One that made me laugh recently was Hamadryad’s observation that:
for a few months now every time I have seen the phrase “class act” (or any permutations thereof) I have mentally substituted “pile of shit.” At least 4/5 of the time it ends up being far more accurate than the former
Muad’Dib started the thread that first used that immortal phrase but he disclaimed authorship
To this day I still use the phrase “gang of blind monkeys drunk on Kahlua” from the Random Box of Evil thread a few years back.
Yes, I know it is a zombie thread, but it popped up when I was searching for a particular quote about working for a corporation:
“You’re probably going to spend ten, twenty, or more years of your life working for a company that’d kill you and sell your organs if it got the CEO a third gold-plated bathtub for himself and his hookers.” – GMRyujin 29April04
My contribution is how Lieu described being wacked in the balls: It’s like if a monkey crawled in through your anus to punch you in the throat.

I’ve had someone beat me to the punch and post the exact thought I was having more than once, but I’ve never seen someone beat me to the punch by thirteen years before. I’ve gotten a surprising amount of use out of this phrase over the years.
I laughed so hard at this thread title I almost hurt myself:
On a thread about the world’s most ugly car, Terrifel posted:
I believe the actual quote was “Someone should tell her it’s a vagina, not a clown car.” When I was in real estate, I would use it for people who came to us looking for an apartment on subsidy for them and their ten or more children.
ETA: The “banhattan” one always makes me laugh.
It took a bit of searching, but here is the original “banhattan” thread.
I always liked Cecil’s, “If ignorance were cornflakes, you’d be General Mills.”
I wish I’d said:
Wow, I even forgot I said that in the OP’s quote.
“May the agony of your death be exceeded only by the glory of my countenance”.
And the only place I find that quote on Google is where it’s attributed to me. Did I really make that up? Wow.
“Tastes like Leprechaun, only gamier!”
Wilson, in this thread, second post.
Still remember it after all this time. 
I wish I was as good with a comeback as a six year old.
From a classic holiday dinner thread:
Wendy: Ben is stupid.
Ben: Shut up, YOU’RE stupid.
Wendy: Ben’s a stupid head.
Ben: Oh really? Who got a high distinction in the Australian maths AND science competitions, scoring in the top 1%? HUH?
Wendy: … (quietly) Ben eats stupid food for breakfast.
Back in 2012, there was a thread about the death of Whitney Houston and the hard life she had and the bad men in her life.
In reference to one of these men, Sampiro offered this one-line post —
“If this guy’s Raggedy Ann could talk, we’d all run in horror at the reason for those patches.”
I enjoyed many, many threads and stories from Sampiro over the years, and his writings are some of the best I have seen here, but that line really struck me and stayed with me over the years.
I can only wish that I could write so well.
