Carl did the bump and run on Kyle to take the lead and win. Which is normal at Bristol. Then when it was over Kyle was still a little hot about it and ran in to Carl's driver side door. So Carl then came down on Kyle's rearend and spun him around. Carl stopped at the start finish line and proceeded with his patented back flip. :thumb

You can go to nascar.com and get the interviews of Carl's version and then get Kyle's. I like Carl's better.
