"Is there life after death. Trespass here and find out." // Well, I find this life too valuable to test it. Besides, only people having the opposite hypothesis will ever find out if their hypothesis was falsified .
I know this is probably supposed to be some funny "no parking" sign, but it reads like surrealism. Park here and your car will simply fall out of existence. No one dares find out. Just stay away from the parking lots.
One thing we read everyday and dont even know about it. Without these signs we more than likely couldnt get around town and know where we are going. I have been lost before driving in unfamiliar places and these road signs helped me out a lot.
