When you start acting like them from seeing so many videos... well, Paul specifically. That adorable thing he's always done where he scratches/tussels his hair and messes it up slightly?... I do it with my hair all the time now. It gives my hair nice volume! lol
I've started doing the George mouth twitch thing without realizing it until somebody pointed it out to me 
And only George can actually me that twitch look good, I just look thick when I do it
