Wearing thin

The Internet is full of April Fool's jokes today. I planted one myself on some online forum, but then, browsing through other websites and encountering lots of April Fool's jokes everywhere, I realized that it isn't really funny (well, one of them was, but only if you like trams and know about the Combino disaster). So whatever you read on any website today, don't believe it. If it's still there tomorrow, it's probably true.
