Mark and Dayna are duking it out again in today's video wars! Mark's pick is a tot who has vocal stylings that rival Fergie Ferg's -- kind of. Dayna's vid features two tykes who know how to get down to "My Humps."
Tell "Extra" -- which "Humps" performance had you shakin' with laughter?
The video wars are back! In the first, a relaxing bike ride ends abruptly when a cyclist unexpectedly encounters a sign! The second video shows why you should never undervalue your parking brake.
