Marcus Smith is in stitches at Adam Jones as Danny Care gives the ex Wales and Lions prop the crying filter treatment. It makes for highly amusing viewing.
Funnily enough, Tik Tok's biggest trend this week comes from rivals Snapchat, whose filter has been used countless times by people around the world. Indeed, the Tik Tok hashtag '#cryingfilter' has been used more than 50 million times.
The filter makes the subject look as if they are crying their eyes out, no matter what facial expression they're pulling. It is quite convincing, and rugby stars have got in on the action. Liam Williams, Marcus Smith and James Haskell have all hopped onto the hysterical trend.
The videos capture players doing something quite ordinary, but it's made so much funnier with this simple effect. Liam Williams is recorded by his partner Sophie sitting on his sofa, and his confusion is outright hilarious.
"You don't look very fine." Sophie says. "I'm fine honestly!" replies Liam.
The couple are in stitches, and it is a similar story at Harlequins' training ground with Care, Smith and Jones involved, while England star Ellis Genge was also on the receiving end from Haskell.
