YouTube Rickrolls Visitors for April Fool's Day

We can remember the days when folks more mature than us reacted to one of our pranks with the warning "it's only funny until someone gets hurt." Since we never bought it back then, we admire the folks at YouTube Australia for promising site visitors a tasty musical treat -- and then re-directing them to the infamous video for Rick Astley's 'Never Gonna Give You Up.' We're guessing that the April Fool's Day idea -- dubbed "Rickrolling" -- was borrowed by a staffer who owns stock in a 24-hour optometry chain. After all, we can't imagine a better way to convince thousands of people to simultaneously stick ten-inch spikes into their eyes ... well, other than a new round of Amy Winehouse nudie shots, that is.
