Ok, here's my personal story:
A few years back while visiting WDW with my parents we were walking around DHS. As we have been to WDW many times up to this point, it baffles me that my family and I had never been on The Great Movie Ride. So, we decided to go ahead and check it out.
As we were walking up to the entrance my dad kept asking us "Is this a ride? Are you sure it's a ride? How do you know?" Um, dad, it's called The Great Movie RIDE! He was so bent on not getting it through his head. We laugh about that still. Every time we go back, whether we ride it or not, we quote my dear and loving father. "Is this a ride? Are you sure it's a ride?"
