Where can I get a sign that reads, "I think 9/11 was an inside job and by the way my parents are related"?

Question

I'd like to get a big sign, about six by six, that is purple and can be seen and read by passing cars on the highway from my padded cell here at Happy Acres. Maybe one that would light up at night so that Bigfoot and the Aliens can read it too. I've spoken with the guy in the cell,,,errr,room, next to mine and Elvis told me that we shouldn't ever give up no matter how many people flaunt their sixth grade education and laugh or throw poop at us. Join me and Elvis as we expose the conspiracy but please throw no poop, I have nightmares enough as it is.

Answer 1

Use the poop and a bed sheet to make your sign.
