The gibberish found in the original post reminds me of a type of spam in which the text is a collection of pseudo random phrases chosen, no doubt, by computer. The phrases look as if they have a common thread or theme, in this case the word "forum" but in reality are not connected.
I've seen them in USENET posts so I am assuming somebody's testing the waters with online web forums as well.
Either that or Yoda is trying to ask how build an amphicar while on drugs.
