'What's My Line?' was one of the great game show's in television history.

Eaxch week, guest's would come on and the panel would only have a certain number of question's to ask before they had to decide what he or she did...what their 'Line' was.

Usually, at the end of the show, a special mystery guest would come on, the panel would be blindfolded, and again they would ask question's trying to guess who this famous guest was.

This week it happened to be the greatest hitter in the history of baseball.
