Trivia: Buck Bokai, a baseball player from the 21st Century, who becomes "real" in this episode, broke Joe DiMaggio's consecutive hitting streak in 2026. While he's not physically seen or referred to by name, this fact is mentioned in the 'Star Trek: The Next Generation' episode "The Big Goodbye."
Trivia: Buck Bokai's baseball card, a collectible featured on Benjamin Sisko's desk, had actor Keone Young on the front, in character, but showed "Trek" model maker Gregory Jein, who invented the "history" of the character, on the back. The pair bore an uncanny resemblance to each other.
Trivia: In the scene where Kira and Dr. Bashir are talking, she points to her pregnant stomach and says "This is all your fault, you know" referencing that Bashir was the one who transplanted Keiko's baby into Kira. This is an inside joke, because in reality Alexander Siddig and Nana Visitor were an item, and Siddig was indeed the father of her baby.
Trivia: In this episode, Sisko, Dax, Bashir, and O'Brien are talking about the amount of Tribbles, and Dax gives the total as 1,771,561, and the explanation behind the total. The conversation was an exact copy of the one between Lurry, Kirk and Spock in the original episode "The Trouble With Tribbles" (TOS, S2: E15).Movie Nut
