Don't know if this is an urban legend or not, but Dr. Ken forwarded it to me and I found it clever, so it works either way:
T. Bubba Bechtel, a part time City Councilman from Midland, TX, was asked on a local live radio talk show the other day just what he thought of the allegations of torture of the Iraqi prisoners. His reply prompted his ejection from the studio, but to thunderous applause from the audience.
"If hooking up an Iraqi prisoner's scrotum to a car's battery cables will save one Texas GI's life, then I have just two things to say":
"Red is positive" - "Black is negative"
