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
