Someone has probably sent you some of Justin Halpern's tweets about his 73 year old dad and all the 'useful' advice he gives. More than a million people follow Halpern on Twitter and now you can read the book Sh*T My Dad Says.

Justin Halpern, who moved back home after being dumped, describes his dad as "like Socrates, but angrier, and with worse hair".

There is also a sitcom coming up in the Fall on CBS.

Be prepared to laugh!
