While the official title of this episode is "Hamsterdam" (after a young dealer's mispronunciation), show runner David Simon stated in an interview it was supposed to be "Amsterdam" (also the title used on the DVD release, but this was corrected for the 2015 Blu-ray release). He mentioned there was in-house confusion about the title that ranged from the directors and producers all the way to the unit producers and set directors.
The Hamsterdam Mixtape - a collection of songs from Baltimore rap artists - takes it name from this episode.
