Lollapalooza is underway, and apparently 100-something kids had the bright idea to all jump the fence at once to get in. Somebody caught it all on video, and it's since gone viral. Security doesn't appear to stop any of them, except for one kid who has a prosthetic leg. The rest seem to make it in, though no word if they ended up getting thrown out later. Watch it all go down above.

Check out our pictures from day one of Lolla, and our guide to 11 non-headliners not to miss at the festival. If you aren't there, some sets are streaming live.
