Do you make plays like this because you have the proper amount of outs and pot odds or because you just like to screw around with people and don't care if you have any sort of hand at all? I understand the idea of owing the table - but how many times has that strategy backfired and you get nailed the first time you go all in like that? That second hand where you got the straight was pure luck. Of course, that's poker.
That's a serious question BTW...
