Thistle!

Seeing this cow with a thistle up his nose, reminded me of Eeyore!

I suppose none of you are sitting on a thistle by any chance?"
"I believe I am," said Pooh. "Ow!" He got up, and looked behind him. "Yes, I was. I thought so."
"Thank you, Pooh. If you've quite finished with it." He moved across to Pooh's place, and began to eat.
"It doesn't do them any Good, you know, sitting on them," he went on, as he looked up munching. "Takes all the Life out of them. Remember that another time, all of you. A little Consideration, a little Thought for Others, makes all the difference."

Sometimes my mind works in mysterious ways!
