At the end of Justice League, we see Clark Kent walking down the street, a subtle nod to the fact that he came back to life too. His “rebirth” scene was cut from the film because watching them put full grown Clark back into his mother was a tad less believable than the mother box jump-starting Superman in the space placenta/embryonic fluid.
Batman asks Superman, “Do you bleed?” This is a subtle nod to the fact that Kryptonian males MENstruate. This line of inquiry is simply Batman trying to get more information on Kryptonian physiology because he is unsure if Superman has gone through “the change.”
Batman did NOT ask Wonder Woman because he didn’t want to get kicked in the pee pee.
Bill Murray (Bill Murray) is asked why he was in the fictional film Garfield 3, to which he answers, “Drugs cost money.” This is a subtle nod to why anyone was a part of the actual film Zombieland: Double Tap.
During the heavy rains, the Kim family’s half-basement apartment floods. This flooding causes the sewers to back up, which in turn sends human effluent spraying out of the turlet. This, quite literally, is a shitty movie detail.
Furthermore, as the eponymous title suggests, there was at least one parasite in said sewage.
