Here it is. The 40 year old tantrum. Kathy Sterner posted this clip of her husband lip syncing to his daughter's temper tantrum.

"My 6 year old daughter had been in her room wigging out for about an hour, and there was no talking her down," she wrote in the description. So Dad decided to "lighten the mood."
