A new phone prank

We used to have water fights on our way out with saline flushes and toomeys filled with water.

We had a nurse recently come in and go get a clean fracture pan. I wondered what the heck is he doing? (this nurse is a pratical joker) He placed it on the desk. I was just about to lean back and another nurse stopped me. I looked and it had something resembling poop with kleenex in the fracture pan on the counter. I told him to clean up after himself, he took it and dipped his finger in the "poop" and tasted it. It was some kind of thick thick soup. I knew it wasn't poop but couldn't tell what exactly it was until he told me.
