“What is hung on a wall, is green, and whistles?”
“…. no idea. I give up. What is it?”
“A herring!”
“but herrings are not hanging on walls”
“This does. I hung it myself”.
“they are not green either”
“This one is, I painted it, if you saw it you’d see the green paint is still wet”.
“And how does it whistle?”
“haha it doesn’t. I added that to confuse you.”
I maintain it’s plastic, chometz, fleishig coca-cola 😀 Now better I get back to cleaning.
Oh wait! I Know the answer!!!
It is the chometz, or should I say, garbage, we are trying to clean up.
(For #1 I would say, it is not living, even though it sure looks like it does. And, #4, some make decoration out of it, dough with lots of salt which does not spoil, becomes hard and can be painted)
