Minor league baseball teams have the weirdest promos. The Jumbo Shrimp — Double A affiliate of the Miami Marlins — are no exception to this rule. in honor of “You Might Be The Father’s Day,” on June 15, the club is distributing pregnancy tests.

Then any fans who received said pregnancy tests can return on Sunday, June 18, for the Father’s Day game to find out the results of those tests.

“It will be an evening filled with suspense, intrigue and manila envelopes,” reads the promo, which was shared by Alyssa Lang of First Coast News.

Any baseball fans who might be thinking they have a baby on the way and want a crazy story to share with the grandkids about how they discovered the pregnancy should make their way to the Baseball Grounds of Jacksonville for Thursday night’s game.

Then Sunday night’s game should be quite interesting, and we’ll be watching this developing story with no small amount of interest.
