The hotel staff decided to call the cops after smelling "a strong whiff of cannabis" coming from the room. When they showed up, Johnson was allegedly spotted wearing a bra while attempting to fill up the bathtub with potatoes, which authorities would later speculate -- in the understatement of the millennia -- may be what "led officers to believe that he was intoxicated." As for why he did it, Johnson later claimed that "it felt like the right thing to do at the time," and frankly, we're not here to argue.
The cops also discovered a whole grab bag of illegal drugs on the scene including MDMA and the hallucinogens 2CB and 5-MAPB. In fact, they actually found enough to charge him with intent to supply, so it's safe to assume Johnson's potato-tub stunt wasn't simply the product of smoking too much weed, according to a report by Munchies.
