Who in the band would you least want to mess with?
Liam: I'm the most chilled out, but if it got down to it, I could also be the most angry.
Louis: He's got two extremes. He can be, like, laughing his head off one minute, then he switches.
Liam: So basically I have a split personality and I'm a psycho. I had a pretend fight with the tour manager yesterday and I put him in a headlock.
