    Lists are nice. It gives PhD's and interns something to discuss while the rest try to survive.

    Mrs. Davidson's dishwasher quit working, so she called a Repairman. He couldn't accommodate her with an evening appointment, and, since she had to go to work the next day, she told him: "I'll leave the key under the mat. Fix the dishwasher, leave the bill on the counter, and I'll mail you the check. By the way, don't worry about my Doberman. He won't bother you. But, whatever you do, not under any circu mstances talk to my parrot!"

    When the repairman arrived at Mrs. Davidson's apartment the next day, he discovered the biggest and meanest looking doberman he had ever seen. But, just like she had said, the dog just lay there on the carpet, watching the repairman go about his business.

    However, the whole time he was there, the parrot drove him nuts with his incessant cursing, yelling, and name-calling. Finally the repairman couldn't stand it any longer and yelled: "Shut up, you stupid ugly bird!"

    To which the parrot replied: "Get him, Spike!

    @portland tony
    well said.
    Do wars & their aftermath contribute to pollution in any manner?
    During Iraq war, reports came out (immediately suppressed) of nuclear tipped artillery shells used all over the place and their long lasting effects on habitat.
