That's the danger of a paper dictionary: You look up a word ... and then read another word ... and another ... and an hour later, you've forgotten what you went to look up in the first place. It's kind of a physical implementation of the tvtropes.org time sink. Or maybe tvtropes should be called a temporal black hole.
For good or bad (depending on whether you're trying to actually get somewhere with the book, or just want to go dictionary surfing) the usual electronic dictionary doesn't do that. It just gives you a cold, bare definition, and where's the fun in that?
Groucho, knock it off with the insults. They're getting more childish by the minute.
