Status: Partially Found
Who Knew? is a game show pilot that was taped at Nickelodeon Studios at Universal Studios in Orlando, Florida sometime in 1998.
The only known footage of Who Knew? online is in a 5-minute compilation video created by former crew members of Nickelodeon Studios for its 10 year anniversary in 2000. There are around 5 seconds of video without the original audio. There is very little information about this pilot available, and whether or not Nickelodeon still has this remains unconfirmed.
