Super Junior’s Leeteuk recently revealed his own phone number as an April Fools’ Day prank on himself. He tweeted, “0101-4460-xxxx”. Moments later, he added, “Within 5 minutes, I got 200 calls”.

Envious of Leeteuk, Kim Heechul posted a proof shot of Leeteuk's phone screen along with the message, “Leeteuk’s phone. He posted his real phone number because it’s April Fools’ Day. His phone blew up. This is what you call a real April Fools’ Day event. I can’t win over that.”

The screencap of Leeteuk’s phone shows badges of 241 unchecked messages, 999 unchecked Kakao Talk messages and 100 unanswered calls. So many people called his phone at the same time that it broke down due to an overload.

Meanwhile, Leeteuk’s tweet containing his phone number has since been deleted.
