Actor Michael Tse was caught on camera drinking his own urine from a bottle.
However, he did it on the show Survivor Games hosted by Bear Grylls, known for his popular series Man vs. Wild.
In Survivor Games, celebrities, including Janine Chang, Andy Zhang and more, are sent on a survival trip and have to live for a few days with limited supplies.
According to JayneStars, Bear Grylls tasked the guests in the final episode to urinate into a bottle and drink their urine the next day.
Many artists struggled with the task -- except for Michael who appeared relatively calm and drank all his urine in one sitting.
He said: "It's absolutely disgusting but in a situation where there's no other option, you're going to have to face it. This was the message that Bear was trying to get across."
When asked about drinking his urine, he expressed: "The smell was horrible, but once I knew it was my own, I didn't find it all that difficult to get through. I didn't do much pondering. I drank it quickly to get it over with."
