Urine test !

Banta had been in the hospital for days. His nurse was extremely annoying and he couldn't take much more.

One day during breakfast, he took his apple juice container and poured it into a urine specimen cup the nurse had insisted he fill.

The nurse came in to check on him and looked at the specimen glass.
In her annoying voice, she snickered, "It seems we are a little cloudy today."

Banta put on his angry face, snatched the bottle out of her hand and drank it down in a few quick gulps, saying, "Well, I'll run it through again and maybe it will come out clearer this time."
