When Bat-Mite zaps Batman because he doesn't look cool enough he transforms him into various incarnations of him throughout the years including the vampire Batman from Bloodstorm, Bat-Hombre from Batman #56 (1949), the Adam West 60s Batman, the Batman Forever (1995) Batman, Zebra Batman from Detective Comics #275, and Frank Miller's The Dark Knight Returns.
The shot of Bat-Mite as Batman appearing on the rooftop, silhouetted against a red sky, is the opening shot from Batman: The Animated Series (1992). The series theme plays in the background.
Batman mentions a "friend in Metropolis" who has dealt with beings like Bat-Mite before. This is a nod to Superman and his 5th-dimensional opponent Mr. Myxzptlk, who possesses many of the same reality-warping powers as Bat-Mite does.
The creators and crew of the show appear in the panel that Bat-Mite moderates at a Fifth Dimension convention. They are sitting and wearing the same outfits they had on at the 2008 Comic Con in San Diego. The crew that appear are Andrea Romano, Diedrich Bader, Michael Chang, Ben Jones, Brandon Vietti, Michael Jelenic, James Tucker and Sam Register. Paul Dini, who wrote the episode, and Warner Bros. producer Bruce Timm also make cameo appearances in the episode, in the audience dressed as Harley Quinn and The Joker. Dini, who was dressed as Harley Quinn, made a similar cameo in the Batman: TAS episode "Joker's Millions."
The scene where Bat-Mite confronts Batman's enemies is taken directly from the 1945 cartoon The Great Piggy Bank Robbery (1946), starring Daffy Duck as "Duck Twacy," a parody of Dick Tracy. This episode's writer, Paul Dini has already parodied this scene once before, in the Tiny Toon Adventures (1990) episode "Inside Plucky Duck," where Plucky Duck takes on the role of Bat-Duck.
