Is your dad a violent alcoholic psycho? If so, then buy him this for Father’s Day:

A book that contains loads of violence, whisky, drugs and swearing. If your dad doesn’t read books, then perfect! I’ve lost count of the number of times numbnut dads have come up to me and said: “I don’t normally read books, but I read Smokeheads and it was great!”

So, there you go. The perfect Father’s Day present for dads who love fucked up shit.
