haha, now i remember that guy!! that was funny, and yah, saying those words, not a good idea, ever, sort of like when someone says "what does this butten do?" or "you and what army?" or "would i ever steared you wrong?".
also the answers for those questions, in order; "ruin everything, completely", "the army that just came out of nowhere" (or sometimes "the army that's right behin- oh crap they're all gone, OH CRAP I'M GONNA DIE!!!!"), and "yes"
