I was poking around Reddit earlier today, and user blabla1624 dropped a doozy in the San Francisco 49ers sub-reddit. The video above is from a 1993 episode of Family Feud. In it, NFL players made an appearance to raise money for charity.
The show featured AFC and NFC players split up by conference. The NFC roster included former 49ers quarterback Steve Young, and former 49ers head coach Jim Harbaugh, who at the time was playing quarterback for the Chicago Bears.
The video is a little over 20 minutes long. Young and Harbaugh make several appearances.
