I remember last april fools day. I went to this site:
http://www.pbs.org/wgbh/nova/vikings/runes.html and I translated the phrase "Up Yours" into Norse Runes. Then I chiseled the runes into a stone. After that, I put the rock into the plastic sink that's down here. When it dried, I took some dirt and smothered it onto the rock, then I wet it again, dried it off, and asked my brother to translate it. When he found out what it said, he started laughing for five minutes before suddenly getting angry. I'm lucky he didn't sent me on a one way trip out the window!
