Athletes Involved: Cal Ripken
According to this one, Ripken let Costner—a friend of his—stay at his house in 1997. During this stay, Ripken found Costner in bed with his wife. Ripken then proceeded to kick the living daylight out of Costner, who pressed charges.
Since a Ripken arrest would have ended his consecutive games streak, this theory says that the Orioles canceled that night’s game—citing an electrical failure at Camden Yards—to keep the streak alive (the Orioles actually did cancel a game in 1997 for this reason). No arrest records have ever surfaced, and Ripken denied the Costner legend in 2008.
If you think this theory is a little implausible and farfetched, that’s probably because you’re a rational person.
