Compact laser deluxe
From Tardis Wiki, the free Doctor Who reference
The Compact Laser Deluxe was a powerful laser weapon that is extremely small, this was proven as Captain Jack Harkness managed to store it rectally, in case of emergencies. It fired a single laser bolt which explodes on impact. Its only known carrier is Jack Harkness and it is used by him to destroy both the robots Trin-e and Zu-Zana. (DW: Bad Wolf)
