A funny joke is badly needed!

Xiaodong and Obana Xiao Li went to the park to play. Suddenly, they saw a pile of feces. Xiaohua looked at it before collecting money and said, "This seems to be a piece of shit." Xiao Li touched it with his finger, smelled it and said, "It stinks." Xiaohua made a little by hand, tasted it and said, "That's right! This is dung! " The three men jumped away quickly, breathed a sigh of relief and said in unison, "It's a good thing we didn't step on it."
