His Father's Son 

An Englishman an Irishman and a Scotsman were in a pub, talking about  their sons.

My son was born on St George's Day," commented the  Englishman. "So we obviously decided to call him George."  

"That's a real coincidence," remarked the Scot. "My son was born on St  Andrew's Day, so obviously we decided to call him Andrew."  

"That's incredible, what a coincidence," said the Irishman. "Exactly the  same thing happened with my son Pancake."
