While being too short is, apparently, grounds for expulsion from Major League Baseball, dropping your pants isn’t. On July 16, 1990, Chicago White Sox first baseman Steve Lyons bunted and, sensing a close play at first, slid to avoid a tag. Lyons made it to the base safely, but his pants didn’t. The slide caused dirt to get between his pants and his underpants, and that’s uncomfortable, right? Lyons, absentmindedly (one hopes!), dropped his pants to brush the dirt off his underwear. He quickly noticed his error and pulled his pants back up, and was not ejected from the game nor suspended for this PG-13 display.
