This isn't a weird thing a GP said, but a stupid thing that a brainless theme park employee said, but it will work in this thread.
So, I went to Legoland yesterday as usual when this one games employee asked this person, "Did you ride the X-Factor ride yet?" and the women said, you mean "Project X".
Brainless employee outsmarted by a typical GP...
(For those who don't know, Project X is one of Technic Coaster's many names)
