This man discovered that putting a train ticket in your mouth gives you an instant cartoon smile and made a funny video to prove it.
Gustavo Reginatto uncovered the trick while travelling on public transport in and around Limerick, Ireland.
He explains in the video that not only does the ticket get you around town, but also gives you a smooth smile.
Gustavo then proceeds to insert the ticket into his mouth, with the white on the back of the card acting like teeth.
The result is a radiant, cartoon-like smile in a hilarious picture.
Gustavo said: “It’s weird to describe, but I use a train ticket to get a nice and smooth smile.
“I received more than 2k comments in 2 days on tiktok, most of them laughing and greeting the video.”
