Last year, Barack Obama threw out the first pitch at the Washington Nationals home opener, continuing a tradition of Presidents throwing out first pitches that stretches back to William Howard Taft in 1910.

This year, however, Obama is taking a pass on getting the season started with a ceremonial first pitch. Instead, recently unemployed talk show host Larry King will do the honor before the Nationals' Thursday-afternoon match-up with the Atlanta Braves.

Here are videos of the last three presidents throwing out first pitches for you to compare, contrast and draw your own conclusions.
