After seeing a post by a well known Instagramer offering a $250 Mother’s Day giveaway for the best funny video, Summer Knowlden decided to enter the competition by sending in a unique twerking video captured in her living-room. Unbeknownst to her while filming, her daughter ran up behind, crashing into her rear end and landed on the floor. Summer told Storyful: "My daughter wanted in on the action and that’s when the “booty bump” happened.We often dance around the house when we’re home together so I’m sure she thought it was weird I was dancing without her."
