Yahoo! Answers is Yahoo’s optimistic attempt at making a social answer website. The concept was good in theory, but they must have forgotten that this is the Internet.

Now, the social site become so full of gags and jokes that it’s often difficult to discern which questions and answers are real or fake.

Either way, it makes for a very entertaining Internet destination.

As one of the biggest fans of the web in the late night business, Jimmy Fallon decided to hold a Yahoo! Answers singing session on his Late Night program. During the bit, he and 5-time Tony Award winner Audra McDonald sang some hilarious posts from the answer site to some smooth piano jazz.
