I'm sure we would all make that face when swerving hard to the left to hit a bike rider!
I think the thing that makes it more funny is that Mayf Nutter is more than likely not driving a moving van in that close up. So when the director said " Pretend to drive for a moment, then suddenly do a swerve face!", he DID
a swerve face! 10 out of 10 for effort, ha ha!
He probably received a "swerve face" bonus cheque from Universal.
If you met him in real life and asked him to do it, he would probably say "Sorry darlin', but I like to do my swerve face ALONE!!"
