I remember writing a bot for an online text based adventure years ago that pretended it was a female newbie that followed people around asking lots of questions and praising them for their skills. AI? not in the slightest, but scripts, pre-programmed patterns and social engineering (no learning!). Lots of fun, and it fooled quite a bit of players (for 5-10 minutes) who, as a thank-you, tended to kill her with extreme prejudice every time they encountered her.
Maybe if I write a script that goes ;
"Hello, this is Thomas's mother, hes 2 years old..."
and then continue to spew out random letters -- would that pass a Turing test?
