Super Junior's Heechul recently busted out his comedic side with a Super Junior joke on Twitter! On July 31st, Heechul tweeted, "On our way to go play! What do you get when Siwon and Donghae sleep? Jamwon-dong!" along with a couple selcas of himself with Siwon sleeping and waking up in the background. [Jamwon-dong is a neighborhood in Seoul which combines the word sleep (jam) with Siwon and Donghae's name]. Heechul later posted another joke that read, "What do you call a breakup when someone says, 'Let's breakup,' and walks away?" without leaving an answer. In response, fans commented, "Oppa, where are you going?", "What's the answer? I'm curious", and�"Siwon oppa woke up!" Meanwhile, Super Junior will drop a music video teaser for their newest track "Mr. Simple" later today. Stay tuned as we bring you updates! Source: Money Today Star News via Nate News
