Not dumb, but just kind of odd. Every time I have a new group of people over at least one person will talk to me about all the magnets under the playfield that keep throwing the ball out of play. I do have SM, Shadow and TZ, but not TAF or LAH or anything which might actually do what they describe. I'm not sure if they think the slings are magnets, don't understand ball spin can be a factor, or just don't want to acknowledge that poor play might explain the drains? I've stopped correcting them and just say "Yep, damn magnets." Just easier not to argue.
