Why is it called a "trap door"? it's a bloody entrance. if it were a trap door that would imply there is some sort of booby trap. — Preceding unsigned comment added by 86.174.144.100 (talk • contribs) 04:25, 21 February 2011
 * While the term "trapdoor" does sound like it should have something to do with a trap, the term actually refers to any door that is set flush in a floor or ceiling. ~Super Hamster  Talk Contribs 05:22, 21 February 2011 (UTC)
