The Ultrasonic Screwdriver is a reference to the Sonic Screwdriver used by The Doctor in the Doctor Who body of work. Want your own? ThinkGeek sells ’em. I linked to the Eleventh Doctor (Matt Smith 2010-?)’s version that was made by the TARDIS after the Tenth Doctor (David Tennant 2005-2010)’s got very borked during the fight with Prisoner Zero, but they also sell the Tenth Doctor’s version if you’re interested.
