Video: Mark Ruffalo discusses his very strange poo-related phobia

Mark Ruffalo, Elizabeth Olsen and Jeremy Renner were all on The Graham Norton Show last night talking about their phobias.

We had the usual 'teeth falling out' fear that wakes everyone up in a sweat every now and again, but Mark Ruffalo's is truly bizarre and makes us wonder what type of friends he had growing up. It must be where the saying 'shake a sh*tty stick' comes from. All in all, this segment is great laugh. We'd say there were a few drinks taken, not least when Ruffalo insults his fellow guest Josh Widdicombe around the three minute mark. Ouch. https://www.youtube.com/watch?v=hD2CJXUwFuo
