Yahoo! Answers loop
When you answer one stupid question on Yahoo! Answers, and you continuously click the "Show me another" button until you finally run out of points to answer with or snap out of your daze. Similar to the Wikipedian loop or YouTube loop.
An unintentional Yahoo! answers loop may start with one question...
*Would you tongue kiss someone if they had food in their mouth?
And then suddenly you're answering more without thinking...
*Who else had pancakes for breakfast?
*Does anybody remember the Angry Beavers?
*Can I join the Army even though I'm a drug addict?

*Questions actually taken from Yahoo! Answers.
