When Liz meets with the Germans, she is wearing the same outfit she wore in the pilot when she first met Tracy.
This episode and Ludachristmas (2007) have no official titles like all other episodes of the show, because of the on-going writer's strike that started in 2007 and ended in April 2008. Apparently, the strike started before the writer's were able to come up with titles for the two episodes.
The episode won an Emmy Award for Outstanding Sound Mixing for a Comedy or Drama Series (Half-Hour) and Animation.
At the end of the episode Gladys Knight makes a guest appearance. The song "Midnight Train to Georgia" was originally by "Gladys Knight and The Pips". Knight is a member of The Church of Jesus Christ of Latter-day Saints wherein members do not drink coffee or alcohol.
