Safety

This is the warning inside of Disneyland's Disneyland Railroad.
That's not a typo.
I know I could just call it Disneyland's Railroad, but that would be wrong.

Anyway, look at the two duos depicted.
On the left it's the safe couple. Sure, they are safe, but are they having fun?

I doubt it.

Maybe they are just nervous and that’s why they are holding hands. Maybe they are romantic. I am not sure.

On the right, THAT'S A PARTY!!!

Look at it! They are having such a good time, they might be dancing. It might even be 'The Safety Dance' after all they aren't wearing hats (obscure joke alert! The Safety Dance was a hit song by the group Men Without Hats.)
