You'll laugh, you'll cry. But most of all, you're likely to share

It's only the middle of May, but already we've had some runaway viral hits in advertising this year. Unruly Media, which runs the global Viral Video Chart, has just released a list of the most-shared ads of 2012 (so far). We've posted the top 20 below. It's a varied group of spots—with dancing and singing, cursing and fainting, running and good old-fashioned pitching. President Obama even makes an appearance. Check out the full list after the jump. And don't resist the urge to share.
