Why would anyone punch Kyle Busch?  Well, there is a laundry list of reasons, but in the end, it will cost you.  I don't know if it's the heat, but NASCAR has seen more than its regular share of off-track brawling this season.  Normally, it's the drivers, but this past weekend, one of the sport's biggest owners got in on the action.  On Monday, NASCAR fined owner Richard Childress $150,000 and placed him on probation for his post-truck race scuffle with Busch after Friday night's O'Reilly Auto Parts 250 in Kansas.  The probation includes all NASCAR sanctioned events through the end of the year.  Did I forget to mention Childress is the owner of Kevin Harvick's team?  Harvick and Busch tangled a couple of weeks ago at Darlington.  The ovals may have to be switched to circle squares if this keeps us.  Both Harvick and Busch remain on probation until June 15th.  Simmer down boys!
