Can I help you sir

An Irish man went to the courthouse to change his name legally changed.

When he replied, the desk clerk asked “Can I help you sir?”

Our man said “Yes, I would like to change my name.”

“What is your current name?” asked the clerk.

“Martin bastard,” replied the man.

The clerk laughed, and said “I can see why you want a change. What would you like your new name to be?”

“Tim.”
