Haha I've always loved that one, its just the way it was so badly worded haha.
One train station I went to they had a sign saying something like "No Passengers are to be alight" and it just made me think....why would anyone just stand there on fire at a station
oh and theres a classic one in my town that starts"Children Don't Think...." its great haha its just the way its worded makes all children sound stupid. My band found it on our way to where we were going to be taking band photos, I'll ask if they took a pic of it.
