Wales rugby international Sam Cross has gone completely viral on TikTok in a video which shows him inhaling methoxyflurane on the sidelines.
The moment occurred in a match between Ospreys and Sale Sharks in the Champions Cup back in January 2022.
The Sevens star had picked up a serious leg injury just before the half time whistle. He was stretchered from the field and put in to a leg brace before being given 'the green whistle'.
It's a piece of medical apparatus that players who have experienced serious injuries are all too familiar with.
The 'whistle' contains a branded form of methoxyflurane called Penthrox, which offers immediate pain relief. The drug affects the brain and spinal cord, making the subject less responsive to pain.
Cross can be seen inhaling the drug and making funny faces on purpose, which makes for quite the comedic moment. The commentators found it hilarious.
"Here's Sam Cross, knee brace on... Haha!" exclaimed commentator Alastair Eykyn.
The co-commentary team of Sam Warburton and Danny Care also couldn't hold their laughter.
You can watch the unique moment below.
Cross was capped by Wales in 2017 after just a few games playing 15-a-side rugby.
The video has done crazy numbers on TikTok over the weekend, racking up 4.7 million views since it was posted five days ago.
It's safe to say fans found it hilarious, and others even told stories of their own experiences with the infamous 'green whistle'.
"I just had one of these after suffering a thigh injury. I can conclude they are this good," said one.
