Rafer Johnson Maria Shriver tavern Robert F. Kennedy sunglasses

It's "take your hero to lunch" day for Maria Shriver!

Looking chic in an LBD and tweed jacket, California's former First Lady escorted Olympic gold medal decathlete Rafer Johnson to lunch at The Tavern on Tuesday afternoon, and their friendship actually dates all the way back to 1968!

Johnson was not only the first black African to win the gold medal for the 100-meter dash at the 1960 Olympics in Rome (while barefoot!), he also helped capture Robert F. Kennedy's assassinator, Sirhan Sirhan, at the Ambassador Hotel in LA on the night Bobby Kennedy won California's Democratic primary.

The athlete reached the gun-wielding killer first, grabbed the weapon and pinned him to the ground before authorities captured him. Shriver has forever been grateful to Johnson for attempting to save her uncle, so we're betting lunch was her treat!
