（1）为什么电锯男的登场地点在捷克
robot
1923, from Eng. translation of 1920 play "R.U.R." ("Rossum's Universal Robots"), by Karel Capek (1890-1938), from Czech robotnik "slave," from robota "forced labor, drudgery," from robotiti "to work, drudge," from an Old Czech source akin to Old Church Slavonic rabota "servitude," from rabu "slave" (see orphan), from a Slavic stem related to Ger. Arbeit "work" (O.H.G. arabeit). According to Rawson the word was popularized by Karel Capek's play, "but was coined by his brother Josef (the two often collaborated), who used it initially in a short story." Robotics coined 1941 in a science fiction context by Isaac Asimov, who proposed the "Three Laws of Robotics" in 1968.
也就是说，现代语中的“机器人”一词发源于捷克，漫画中所出现的泥人村，还有巨型的自动泥人，可能都是为了纪念这个事实吗？
（2）囧剑excalibur
Excalibur
King Arthur's sword, c.1300, from O.Fr. Escalibor, corruption of Caliburn, in Geoffrey of Monmouth (c.1140) Caliburnus, probably a variant of the legendary Ir. sword name Caladbolg, which may be lit. "hard-belly," i.e. "voracious."
所以看来，首先那本叫excalibur的书还真的是存在的（只是历史上叫Caliburnus，ex是后来传抄过程中附加上去的）...而且那把囧剑说的“我的传说始于12世纪”也很准确（历史上是最早出现于1140年）...
