Korean-American Jay Park recently launched a collaboration with "Engli Star" (?????), a website for Koreans to learn and practice the English language. For his first episode, Jay switches from singer to teacher as he gives viewers a lesson on amusing English expressions -- more specifically, how to hit on guys at a club! "Ten year olds aren't allowed at clubs. I'm sorry, please study well at home," he warned sheepishly, continuing later on, "and forty year olds shouldn't go [because they have to] raise their children!" With that said, check out some of the phrases he taught below! [embed]http://www.youtube.com/watch?v=ASbQbrX4FtU[/embed] Source: Youtube
