The moment the situation at Red Bull pretty much went nuclear.
Sebastien Vettel has gone from a likable, funny German to an evil, selfish superiority complex German while Mark Webber continues the sort of underdog performances you expect - though it does mean that Advance Australia Fair is completely and utterly unavoidable.
What could have been a boring Red Bull benefit exploded into life around the first corner and never looked back (neither did Webber). Even Pedro de la Rosa leaving bits of his rear wing on the Northamptonshire/Buckinghamshire border couldn't stop him. Nor could the new layout with the speedbump in the middle of it.
In NASCAR-land it appeared to be a sport as unpredictability broke out as someone not from Hendrick, Gibbs or even RCR won a race.
NASCAR had to take a week off to recover.
