Wikipedia, as everyone knows, is really a digital black hole from which there is no escape. Why must it be so...so...INTERESTING?! I mean, an online encyclopedia? Come on, right? But no, it's a subtle beast. First you go there looking up something innocuous, like the Battle of Bunker Hill for a homework assignment. Then you notice a link to, say, snipers, then assassination, then....well, let's just make a chart:
Battle of Bunker Hill --> Sniper --> Assassination --> Warring States Period --> Pinyin --> Grapheme --> Orthography --> Japanese writing system --> Meiji Period --> Rurouni Kenshin
EDIT: Fifteen hundreds and counting! As a reward for your appreciation, I give you:
Battle of Bunker Hill -> Hessian (soldier) -> Germany -> Roman Catholic Church -> Jesus Christ -> Western civilization -> United States of America -> American Revolutionary War -> Battle of Bunker Hill.
