It's Super Mimi! AKA Mimi on Crack. Sometimes she gets a little bee in her bonnet and she runs around like a crazy person dog. And all you have to say to get her going again is "I'm gonna get you!" and she's off like a shot!
I can't get the video to load so please see Super Mimi here on You Tube.
P.S. Ignore the blankets everywhere...I've been sick...and lazy.
