In its opening sequences, The Beach Bum introduces Matthew McConaughey as dirtbag prophet Moondog, ambling around Key West, high off his fucking gourd on a combination of what's likely some potent weed and an endless series of PBR tall boys. One moment, he picks up an adorable little kitten and reads some poetry on a bar stage. Another, he's out to sea, on a boat, flanked by topless women and beating a drum. It's an evocative image, not just because of director Harmony Korine's dreamy 35mm footage, but because of what we know about Matthew McConaughey. The man freaking loves to get naked and rhythmic.
As crucial to the idea of Matthew McConaughey as Dazed and Confused's Wooderson, True Detective's Rust Cohle, or the guy from those Lincoln ads, are the facts of his real-life arrest in 1999. On an October day, a complaint about loud music led police to find the actor in his house dancing around with only a University of Texas bandana on his person. There was reportedly a bong on the table, and yes, McConaughey was banging on the bongos. According to the Associated Press, he was arrested on "on suspicion of possession of marijuana, possession of drug paraphernalia and resisting transportation, according to a police statement." There was an unidentified man supposedly clapping and cheering him on, and while he was briefly detained, he wasn't brought to jail. The biggest mystery of the night, therefore, is still: Who was the man hanging out while McConaughey played bongos in the nude?! Why haven't we heard HIS story?
Ultimately, McConaughey was only charged with resisting transportation. He really didn't want to put on his pants. While the report doesn't say that McConaughey was high off his balls while letting said balls hang out with some bongos, that's very much implied. He eventually paid a $50 fine. All in all, the punishment probably fits the crime.
