LEGO Batman Movie: 75 Easter Eggs & References You Need To See

24. Phantom's Own Laundry

When The Joker goes to the Phantom Zone, Harley Quinn plans to steal the Phantom Zone Projector and release all of the villains, dusgusing herself once more and driving a laundry truck with the company Phantom's Own Laundry emblazoned on the side. Subtle.

If that wasn't enough, the truck door reads "Operated by Quinzel", to give everyone at Arkham even more of a hint of what's going on.

23."No Stationery"

Batman ends up being locked up in Arkham Asylum when he sends The Joker up to the Phantom Zone, and if you look closely each of the prison cells have a sticker on the window reading "no stationery".

Given what The Joker did with a pencil in The Dark Knight, that shouldn't at all come as a surprise.

22. Suicide Squad Shade #2

When The Joker's plan is enacted and he and the super-villains from the Phantom Zone invade Gotham, Barbara Gordon tries to suggest that it would take a team of villains to tackle them.

Batman dismisses the very idea as stupid...
