Liam is afraid of (apparently) spoons, Niall is claustrophobic and has ornithophobia. I think...and we can all bet that they're afraid of bearking up and stuff.
LIAM'S FEAR OF SPOONS!!! one time when he pissed niall off, and niall berkata to another member, "hand me a spoon" Liam's a germaphobe so that's why he hates spoons cuz so many other people with dirty hands has touched them !!!
