Polysemous joke

The following is a joke about polysemous words:

"Last night, I dreamed that I was in a noodle restaurant."

"Oh, what noodles did you order?"

"I want to order pork noodles, but the waiter told me that they don't have pork today, only beef and chicken."

"Which one did you choose?"

"I finally ordered chicken noodles."

"Why not choose beef noodles?"

"Because I heard that there are two cows and one chicken, I am afraid that if I order beef noodles, the waiter will hear' you want to shit noodles'."

This joke uses two similar but completely different Chinese polyphonic words' shit' and' ten' as puns, resulting in some humorous effects.
