At some point before the outbreak of the Sandmen, after a Maha Shivaratri/Oshogatsu/Christmas party, a crew member reprogrammed it not to allow any person entry to a room until they sang the song "Mr Sandman". The computer found it very amusing.
Behind the scenes Edit
The computer was voiced by Nikki Wilson, who was the producer of the TV episode in which it appeared. She said, in a behind the scenes video, that she was having "too much fun" doing the computer during the auditions, which led to her doing it on set.
