I should mention first that you need to take into consideration that many Trivial Pursuit cards are right when they are printed and simply get outdated(world records and things).
What questions have you known the answer to only to find that the makers of Trivial Pursuit are idiots?
The classic question is “What is the only man-made object visible from space?” The answer they give is “The Great Wall of China”. Of course, many objects can be seen from space.
Here’s one I’ve seen. “What actor has portrayed the same character on television for the longest period of time?” Their answer? “Kelsey Grammer.” I’m almost positive the real answer is Carol O’Connor. One thing I do know is that Kelsey Grammer is wrong.
You find any?
