KANSAS CITY, Mo. -- Sometimes staying serious while you're live on the air can be tough, but it becomes even tougher when your co-workers egg it on.

FOX 4's Mark Alford was reading the script Tuesday morning about a yoga studio that is offering naked yoga classes, when the ladies in the studio seemed a bit disgusted.

As the camera angle switched to FOX 4 meteorologist Karli Ritter, she couldn't help but laugh as she told Mark what she thinks would be the worst position for that type of class.

Watch the hilarious moment in the video above.
