Stop horsing around jokes

I had an animal pun contest today. He started off by saying something. I don’t remember.

Then I replied, “TOUCAN play that game.” He went silent, and my other friend barged in and said, “Don’t you think he’s CHICKENing out?” I said, “Yeah, just stop HORSING around!” He came back with one, and I ended it by saying, “Ok, let’s MOOOOOve on cow.”

Welp, that’s it.

What do you say to your pony when it's being wild?

Stop horsing around!

So there was this girl and her horse would not stop following her, so she said, "Stop horsing around!"

Get it? "Horse-ing."
