"The Wolf of Wall Street" is loaded with scenes of people getting high like there's no tomorrow. But there's one particular scene which stands out the most, in which Jordan Belfort and his best friend take an excessive amount of Quaaludes before suffering the consequences.

So how did they pull it off? Apparently, it was inspired by this viral YouTube clip below:

Just like the guy in the clip, the scene required DiCaprio to crawl and roll around on the floor like an imbecile. Here's what else DiCaprio revealed to Bustle:
"We wanted the film to be this hallucinogenic ride, this roller coaster," DiCaprio said during a press conference for "The Wolf of Wall Street" on Sunday in New York. "That scene specifically was almost like a day in the life of two schnooks who took way too many drugs. To me, it was almost like a small film within the film. We kind of treated it that way."

"A lot of it came from me filming Jordan talking to me about what Quaaludes are like. I had him rolling around on the floor for me. That was very helpful," DiCaprio said of his preparation for the sequence. "A lot of the research that I did really came from watching this one video on loop. It's called 'The Drunkest [Guy] in the World.' It's a man trying to get a beer, but his body doesn't quite [work]. That was a huge inspiration to me."
So think about that the next time you laugh at some poor slob going viral on YouTube. You never know when their crazy shenanigans might just end up being in a blockbuster movie!
