Oh Arnie is a man of the Earth. He not only loves his eco-friendly vehicles, but he also loves his wacky tabbacy. Yes, bust out the twizzlers, kids – it’s 420!

According to the editor of High Times, Steven Hager, the term “420″ originated in 1971 at San Rafael High School,  among a group of Dazed and Confused-like pot-smoking students who called themselves the Waldos. They coined the  term to reference the time of day when they would meet up to smoke pot.

Naysayers to this theory claim that 420 originated from a police dispatch code that identified pot smokers. Yet another theory suggests that 420 originated from Hitler’s birthday. Rather than feeling creepy about the Nazi’s April 20 birthday, pot smokers decided to turn their frowns upside down by using the day for a celebration of peace, freedom and Funyuns.
