Double yikes. Christopher Thom is saying he will never get involved in someone elses domestic dispute again.

The 22 year old father thought he'd help a lady out at a party when her ex punched her in the face. Thom stepped in to help and promptly got nailed in the head with a hammer leaving a 6 cm hole in his skull.

Doctor's are waiting to see if he needs surgery as he's got air build up and fluid on his brain. No sign they've arrested the hammer weilding creep as of yet.
