Morganna Roberts (The Kissing Bandit)
Morganna Roberts was a FF list celebrity in the 80's who would show up at sporting events and "accidentally" fall onto the field by leaning her top-heavy body over the railing and let gravity take it's course. Once on the field, she would make her way to a player, plant a kiss on a cheek and scurry off the field.
She performed this stunt at the first night game at Wrigley Field, only to have the game rained out.
When she went to kiss Steve Garvey he ran around home plate away from her to best maintain his squeaky-clean (and phony as it would turn out) image.
Nolan Ryan saw her coming to him and waved her over.
