Yep, his brother Ben swapped his family photo for a nicely framed pictured of North Korea's supreme leader — and his mum was none the wiser for two whole weeks.

Jake told Mashablehe didn't know where his brother got the idea from, but he was surprised by how much attention the tweet received (60,000+ retweets at the time of writing).

Sadly, though, he also admitted that the tweet's new found attention eventually revealed the truth to his mom.

"Someone showed her my tweet," Jake explained. "But she said if she wasn't shown it then it could of been up there for years and she still wouldn't of had a clue."

This isn't the first time someone's had a similar idea, either.
