What are some really stupid questions?

I was in class one time as my teacher was explaining that the Sun was the closest star to the Earth. Then somebody asked "What is the farthest star away from the Earth?" and I was the only one laughing. What are some other stupid questions?

I used to work at McDonalds and someone asked for a chocolate sundae without the chocolate! lol

Why don't they just ask for a plain sundae?
