I (literally) walked into Eric Bana once. Of coarse back then, I only knew him from 'Chopper'. I remember apologizing and saying something like 'you're that Chopper guy?' (I'm a fuckin' douchbag). He chuckled, 'Yeah mate, yeah'. He asked me if I knew where this stage challenge practise was going on at, I told him where, he said 'Cheers' that was that.
Now he's the freakin' 'Hulk'. That's weird. If that same thing happened today I would be a hell of a lot more nervous.
