DM: You see a well groomed garden. In the middle, on a small hill, you see a gazebo.
paladin: A gazebo? What color is it?
DM: [pause] It's white, Eric.
paladin: How far away is it?
DM: About 50 yards.
paladin: How big is it?
DM: [pause] It's about 30 ft across, 15 ft high, with a pointed top.
paladin: I use my sword to detect good on it.
DM: It's not good, Eric. It's a gazebo.
paladin: [pause] I call out to it.
DM: It won't answer. It's a gazebo.
paladin: [pause] I sheathe my sword and draw my bow and arrows. Does it respond in any way?
DM: No, Eric, it's a gazebo!
paladin: I shoot it with my bow. [roll to hit] What happened?
DM: There is now a gazebo with an arrow sticking out of it.
paladin: [pause] Wasn't it wounded?
DM: OF COURSE NOT, ERIC! IT'S A GAZEBO!
paladin: [whimper] But that was a +3 arrow!
DM: It's a gazebo, Eric, a GAZEBO! If you really want to try to destroy it, you could try to chop it with an axe, I suppose, or you could try to burn it, but I don't know why anybody would even try. It's a @#$%!! gazebo!
paladin: [long pause. He has no axe or fire spells.] I run away.
DM: [thoroughly frustrated] It's too late. You've awakened the gazebo. It catches you and eats you.
paladin: [reaching for his dice] Maybe I'll roll up a fire-using mage so I can avenge my Paladin.
