The number "420" has been adopted by marijuana enthusiasts the world over and is thought to have originated in 1971 with a group of buddies from San Rafael high school in California who called themselves "The Waldos".
And even though many stoners have lost sight of the number's origin story they all agree that April 20th is the (un)official day of cannabis celebration, when everyone is in high spirits.
But the people in these news clips don't need to smoke weed to act like total stoners, because they're so high on life it hurts to think! Must be something in the air...
