I lol'd at the title of this thread.
Some people just want to practice with the chance of making some money (even $1) and no risk. Not everyone plays poker to win millions, some just want to have a laugh.
And with no-one limping to get to the money (as it doesn't matter one bit) you get more practice in trying to win the tourney. Alot of players will enter MTT's with big prizepools but freeze around the button trying to cash, you want to aim for the top 3 spots and these low giveaway tourneys make you do that imo.
