Today, I stumbled upon this. It's amusing to say the least; at first i took it seriously but then it clicked, that this was possibly an April fools joke. My suspicions were proven to be true when i took a hex editor to String's bytecode, just to see for myself. I'd just like to say, an April Fool's joke done well Christian!
I cannot talk April Fool's without talking about Google. They have the most creative minds behind them, so it's not shocking they have some pretty imaginative April fool's jokes!
