You guys can't make fun of the General Public too much, you know. It's not like they're extremely stupid or anything. It's just that, as people, we all have certain interests. Some people may love video games, cooking, books, film, etc.
Some of us are basically the "GP" of those things. Just keep in mind that not everybody knows everything in the world. I know this because basically everybody I live around is a "GP". They just like to go to amusement parks sometimes for the fun of it.
But I'll agree, some of these quotes are not just dumb too us enthusiasts, but to normal people, there are extremely stupid things that are said...
Now before I turn into a geek, I'll post many I have heard.
A girl in The Beast station - "Is this a roller coaster?"
A girl near Boomerang at Wild Adventures - "The ride flies off the tracks daily".
Kid in line for Demon at Six Flags Great Adventure - "Coaster Rollers don't get much better than this (points at Demon). Black Bird!"
