White Sox Bathroom Sex: Couple CHEERED On Opening Day

Most White Sox fans presumably went to the team's Opening Day on Monday to watch the team play. And indeed, those who actually watched the game were rewarded by seeing as good a defensive play as one will ever witness. One couple, however, decided to take care of some other business while at the ballpark.

A White Sox fan and his son were waiting to use a bathroom at U.S. Cellular Field when they witnessed some unusual behavior in one of the stalls, according to the Chicago Tribune.

"So I kicked the door, just to get a reaction. I just wanted to make sure nobody was dying in there. That's when I heard a woman's voice yell, 'HEY, STOP!' Something was going on and I had interrupted."

Moments later, the stall door opened, and a tall, thin, blond man exited. The tall man held his arms up in triumph.

It turns out a couple was using the barely private space to have sex. Click here to see the rest of the bizarre details, including the unexpected reaction from others in the restroom.

It's hardly the first time frisky fans have subverted a stadium restroom's intended use. During the Cowboys' first game in their new stadium last year, a couple was filmed going at it in a stall.
