Ewan McGregor's Pilot Brother Tried to Make Him Sick in a Jet Fighter (VIDEO)

There's a tradition among jet fighter pilots of trying to get civilians to throw up in the plane should they ever have cause to fly them around. As Ewan McGregor explained on 'Late Show' (Weeknights, 11:35PM ET on CBS), this tradition is compounded in the worst possible way when the pilot is also your older brother.

His brother shifted altitudes on him quickly and then came the grand finale. "He had me do a couple of things in the cockpit like changing the radio frequency and such," McGregor explained. "So I went down to do that and then he went round a corner."

But that was all it took. McGregor did say he kept matters "tidy." "I folded it down, I crimped it." Of course, then he had to hand his tidy little package to the ground crew while his brother surely trumpeted his victory.
