speaking of colorblindness..:hubba:
A old man i knew once couldn't distinguish red from green at all. He was at the motor vehicle department trying to get his license and they had just implemented a new test for just such a thing. It consisted of 2 columns of numbers. One red column and one green column. The guy says, " please read from the green column", as he is filling out the paper work and not really paying attention. So my buddy figures he's got a 50/50 chance at getting it right, so he guesses and starts reading numbers from one of the columns. The clerk looks up from the paper work (kind of irritated), then back at the columns and says, "NO, from the green column!"
