Makelle and Jared Ahlin of Santaquin said they spotted something unusual as they perused the ultrasound images.
“She kind of went past it, and I was just like, ‘Hey, go back, I need that picture!'” Jared Ahlin told local station KSTU.
In the ultrasound the infant appears to be holding his or her hand in a gesture familiar to anyone who has ever been to a rock concert.
The couple swears the images weren’t altered digitally, and they even have the original paper copies to back up that claim, KSTU reported.
“Our boys are very active I guess, so it probably sounds like they will fit in to the family,” Jared Ahlin said.
“They're pretty wild I would say,” Makelle Ahlin added.
The baby is due toward the end of June and the couple have decided to keep the gender a surprise until delivery.
