As Beast Boy's very first appearance was in Doom Patrol #99 on November 1965, this episode celebrated his 50th birthday.
A Titan's birthday is celebrated once again, in this case Beast Boy's. Cyborg's birthday was celebrated in "Pie Bros".
In the beginning of the episode, Cyborg is seen holding what appears to be a Nintendo 3DS.
The popular song "Happy Birthday" was briefly heard when the Titans start to sing for Beast Boy's birthday, but Robin can't let them sing it. This was used to avoid the song's copyright infringement it has - despite its popularity - and was only used in reality to celebrate an actual person's birthday. Therefore, the episode features a different song, entitled "Beast Boy's Birthday Rap".
