I was watching the finals of this week's Smash: Xanadu on Youtube, and Chudat and Junebug was fighting. Junebug wins 2 straight to reset the bracket, and then wins another one to force Chudat into eliminations. In round 4, in the middle of the match, up one stock, Chudat proceeds to edge guard the stage for 5 straight minutes.
Mind you, Xanadu has specific rules for this, that you edge grabbing is limited to players below 50%, and Chudat started when his Kirby was at 80%. What proceeds is about 7 minutes of trash talking on Chudat, funny jokes, and 141 edge guard attempts. The penalty is that you lose the match unless you are able to take all stocks from the opposing player.

It was amazing to see a player completely throw a match on youtube like this, I can't imagine for people watching the stream live.
