According to High Stakes Report, Gus Hansen recently dropped nearly $800,000 in a 15.5 hour PLO session at Full Tilt,

The great Dane sat down on FTP table Patrik and would not get up for another 15.5 hours as he continued to fall deeper and deeper in the hole. Logging in 1,168 total hands in the $2000/$4000 Limit Omaha Hi/Lo game, Gus Hansen managed to donate over $796K during his marathon session. The other six-figure losers at the table consisted of Ilari “Ziigmund” Sahamies (-$125K), Markus Golser (-$131K), and Bill Gazes (-$158K). The game’s biggest win went to Patrik Antonius who racked up over $476K thru 674 hands. Other big winners were Steve Sung ($219K+), John D’Agostino ($214K+), and David Singer ($123K+).

So the next time you go on monkey tilt and blow through a quarter of your bankroll in one day, smile, it could be a lot worse.
