Halloween is one of the few nights where an absurd opening line fits right in, because everyone is already in costume and nobody is taking anything seriously. This is our collection of Halloween pick up lines, ranked by reader votes — vampires, witches, ghosts, zombies and the usual jokes about things that go bump. They work at parties, in queues for haunted houses, and on anyone who has put real effort into their outfit, which is always a good thing to comment on. Some are sweet. A few are genuinely creepy, though on this particular night that may count as fitting.
