THEY BOTH LICK THEIR PAWS!
Aren't they themselves a carry-on?
The white ones are usually pretty pointless
A police dog in disguise.
A cat-a-logue !
Because they can't make a fist.
Likud.
They both say the same jokes over and over again.
Because freedom rings.
This might be better suited for but I think its more a joke Cats have claws at the ends of it's paws commas haves pauses at the ends of its clause.
To see who shot his "paw."
Accidentally hit submit before you
Because they refuse to Submit to anyone but Allah.
