Hadley is an opinionated douche. If someone doesn't agree with him, they're wrong and to show them that he's 'right' he yells to the top of his lungs so no one can interrupt him.
I remember on some Rugby League Show on tv (I forget now) and Hadley was invited on there. The guy just wouldn't shut up. Interrupting everyone and talking forever... Being the attention seeker that he is and he's a guest ffs. Well anyway, the host had to go to break and he would've been stopped about 4 times from Hadley carrying on. The host was getting very pissed off.
If he's like this on 9, than fmd.
