Here we go go with that wrestling thing again. Put a microphone in front of them and it's a "I'm gonna kill'em" talk, but later you'll find them at a bar having drinks together.
I actually saw this happen once, after an event I stopped for a bite and saw a few of the old time wrestlers (Iron Sheik, Billy Graham, Kurt and Karl Von Brauner) eating at the same table.
Real or not it helps put butts in the seats at a drag race.
