hacked signs

they are doing construction on a street in our development and they have this giant electronic sign sitting there and stu and i were talking about hacking it.  thinking about putting something like "theres a storm coming" or some other useful advice.  i dont want to put anything racist like you mad bro

here are some other ideas people have come up with.  if you got any other good ones, post them on here.
I was going to make this a meme, but i couldnt find enough and i'm not sure its actually a meme.
