Here is some weekend fun. Speaking random quotes from the internet at random intervals. Only tested on my Macbook. Not sure if there is the say utility for other platforms.
while true; do say `curl -s http://www.quotedb.com/quote/quote.php?action=random_quote | head -n 1 | sed s/document.write\(\'//g | sed s/\<br\>\'\)\;//g`; sleep $((RANDOM%60)); done
