We see a street artist drawing a rudimentary cat with a stick in its mouth on the pavement outside the Flat Earth Society.
Three eminent looking types are on their way in when their gaze is drawn to the picture.
MAN 1
"It's a cat!"
MAN 2
"That's hardly original!"
MAN 3
"Whatever is it supposed to have in its mouth?"
STREET ARTIST
"It's called a Boomerang"
The wind ruffled my hair as that passed over 
Clever stuff Teddy. I'm assuming that the cat being perceived as cleverer and lazier than a dog has invented a stick that it doesn't need to chase after. Or have I got the wrong end of the stick........
Earth, gravity, boomerang? If it's that then I think I get it 
Nope not getting this
Although a Dog with a Boomerang might have been nice.
Is it another obvious pun?
I'd be careful If I were you The last one caused Tony Cowards to take the morning off.
This joke is so clever, nobody's getting it. I'm beginning to smell a big rat here.
Sort the wheat from the chaff Teddy. You are posting up too many of these misses now and they are detracting from the genuinely funny ones you put up.
Spent 5 minutes trying to work this out, and have now given up.
It's like watching Inception on a Eastern China airline flight last week.
I have to admit it was a tad conceited of me to pen this,I made the mistake of thinking I am funnier than I actually am.
You have my apologies and I will keep this post up to remind me of my own shortcomings.
