The sword-fighting, tennis-playing Wii-bot (caution: some foul language in the video when the camera operator gets hit by a tennis ball) [you may need to try a few times. it's been slashdotted, and the server's not really coping].
This can only lead to trouble.
Trouble, as in televised duels between wii-mote controlled robots. Not so much the destructive kind of trouble (though those sword moves looked rather menacing).
