    There will always be "Which came first...the chicken or the egg?'

    Or "...the can or the can opener?"

    My fave is always the Steven Wright joke..."If I melt dry ice can I swim without getting wet?"

    Anybody else got some of these?

    If a man says something and there is no woman around to hear him say it, is he still wrong?

    That's easy.

    1. The egg.

    2. The can. read http://en.wikipedia.org/wiki/Can_opener

    3. Dry ice is called "dry ice" because it goes through sublimation in normal pressure conditions - it goes straight from solid to gas, hence leaving its surroundings dry.
    If you were to melt dry ice, you would have do it in a highly pressurized environment. If you will be in a pressure suit, it is logical to assume you won't get wet; if not, you will get wet (as if you were immersed in any other sort of liquid)... and you might also get crushed by the pressure.

    I use dry ice in my martini. Hence dry martini.

    Provided all airspaces in the body are equalised, pressure isn't a problem until oxygen becomes toxic at ~8 atm. CO2 is a liquid at this pressure at about -50C, so provided you can stick the cold for a few minutes, you'd swim around, then start depressurising and/or increasing the temperature and it would simply boil off. Have some burn cream ready though... (the freezing point of water doesn't change appreciably over that pressure range)

    Maybe you are always wrong. Have you considered that?

    If a tree falls on Paris Hilton's head, and no one else is around, will she feel it?

    I think that calls for an experimental investigation.

    Or maybe someone can just hit her in the head with a shovel...but definetly worth looking into!
