Arm-wrestling, like many contact sports, is all fun and games until someone gets hurt.

Megan Weber (alter ego Rogue Scout), a 31-year-old physical therapist from Lewes, Del., and Sarah White (Sweet Treats) were all smiles as they gripped hands at the Delaware Arm Wrestling Lady League, which raises money for women’s issues, according to Delaware Online.

Rogue Scout (Weber) even won against Sweet Treats during the right-handed portion of the competition.

Switching to the left hand, the ladies struggled with gritted teeth before Weber’s arm bent in defeat — literally. White had accidentally snapped Weber’s arm. And a video captured the gut-wrenching scene.

Delaware Online reported Weber saying that while she’ll support women who want to compete, she doesn’t think she’ll be arm-wrestling again.

“I really don’t think it’s a dangerous thing. It was just one of those freak things. I think one time was enough for me,” she said according to the website.
