When Mac Taylor (Gary Sinise) enters autopsy, Sid Hammerback (Robert Joy) welcomes him with "You're institutionalized now." This is a quote from Ellis Boyd 'Red' Redding (Morgan Freeman) from The Shawshank Redemption (1994). He quotes further "These walls are funny. First you hate 'em, then you get used to 'em. Enough time passes, you get so you depend on them. That's institutionalized."
