Carface is implied to have been eaten by a gator as he ends up in heaven at the end of the movie. Charlie is at one point in the gator's mouth but does not get swallowed.
Twice, but SUPER briefly. One of those is a shrug toward the audience, a little “Heh” moment, and the other one happens at the absolute very last moment of the movie, a wink and a fun little remark to the audience; roll credits.
The latter half of the film centers on finding a home for one of the main protagonists, they are shown sleeping in cars in the junkyard various times. Eventually, they are housed.
SPOILER: Bittersweet ending, since the protagonist dies in the end, but is allowed to say goodbye to the little girl he saved and is afterwards welcomed into heaven.
