This is a hilarious use of twitter, this guy is his friends Best Man in the wedding, and swears not to prank them until AFTER the wedding. So while they’re on honeymoon, he installs a pressure sensitive pad in his friends bed which automatically tweets when it detects action on the bed. It reports back the weight/duration/intensity of the action when they’re “on the job”.
Brilliant!
