I can’t wait for the next big catchphrase thingy, I expect I will flip my flippin lid when it happens. As for ideas though, I have none.
edit: Hey! How come half my sentence took on a black hue?
edit#2: Come to think of it, can black accurately be described as a hue?
Will someone change their user name to our winner as well?
“And the kitten played with the ball of string all night long, and in other news a local shop keeper was brutally killed”
why not combine several…
Furious oriental nipples of fire, 1970 style
I put it in the Pit because I was expecting a backlash of, “Why are you bringing that up again? If people keep talking about it, it will never die!!!”
Whatever. If a mod wants to move it, I don’t care.
“Bumper? Sticker? I hardly know her!”
This would look stunning in place of 'FIGHTING IGNORANCE SINCE 1973". Someone suggest it to the Chicago Reader.
I’m also pretty fond of ‘I burning your dog’.
Not that I have any great aversion to the Deaths Rays in ones and twos… I just wish there weren’t quite so many threads dedicated to them.
Or, inspired by Beryl_Mooncalf:
Hi, I burning your nipples!
“Dyslexic knot theorists of the world, unite!”
(preferably using the Reidemeister moves)
I burning your dog . . .
with a 1920’s style “Death Ray.”
Ducks and Runs 
This is rather like trying to get rid of a song going through your head by thinking of Kylie Minogue’s “I Should Be So Lucky.”
I thought we already had a winner:
“What a shocking bad hat!”
And what do we burst things with?
(giggle)
Anyway, my vote goes to “Is that a leg?!”
Wouldn’t that be “untie?”
I like the idea of someone changing their name. In fact, perhaps that would help it jump the shark and go away real quick so we can move on to the next fad.
Not me, I need my name.
I could change my location field to Gallatin, TN, though, and see if anyone finds that amusing.
Or we ALL could. That probably WOULD be amusing.
I suggest “Kantalooppi is a god amongst men and compared to him I am a mere earthworm”.
One of the tasks of a knot theorist is to untie knots. A dyslexic knot theorist would try to unite them instead. It’s a playful modification of the original joke, which said, “Dyslexic people of the world, untie!”
The Reidemeister moves are a set of operations that transform a pictorial representation of a knot into a different but topologically equivalent pictorial representation. I hoped that by including that parenthetical comment, the joke would become obvious. I guess that was wishful thinking on my part.
That gets my vote for the new catchphrase.
I’d buy that for a dollar.
I’m burning down your fish pond.
(No, I didn’t make that one up.)
