My colleagues know how to play gently. Not. As Annekaisa placed a juggling ball on Kalle's head, he picked it up and effectively hit her in the eye from a distance of 10 meters, as this film [1,1MB, MP4, QuickTime-compatible] shows. Bullseye!

The voice at the end is Susanne saying "Kalle, you've just hit a girl! And you might be used to doing it."
