Drupal is known to be geeky (read hard) for casual CMS users. Drupal was all set to change its geeky image with a super cool theme - Garland. WordPress.com's founder Matt Mullenweg asked for free help in porting this special theme to WordPress from the WordPress hacker's community. It was generally perceived as a bad idea in the mailing list. However he went ahead and ported it with the help of one of his employees.
