I recently found some funny clips on YouTube with the Tumba Ping Pong Show, which seems to be a Swedish group performing "extreme ping-pong". They are really funny, and the videos are well made (good looking special effects). They also have the Tumba Ping Pong Show Web site. Their YouTube videos are highly recommended! :-)
Sweden actually used to be very strong in "normal" ping-pong, and managed to take lots of medals in various sport events. Nowadays I do not think there are any world class players, but Asian people still talk to me about Jan-Ove Waldner. Another strong player was Jörgen Persson.
