I love wikipedia, for so many reasons. I have, in my Firefox browser, a direct Wikipedia search box, which sees frequent use. Such was the case when hemisphire recently accused me of being "Hoist by my own Petard." Not only had I never heard the phrase (except in passing in Hamlet, apparently), but I had no idea what was being talked about. Awesome. Never will I watch The Two Towers again without thinking about petards during the orc torchrunner part at Helm's Deep.
I didn't experience the full-on xkcd-wikipedia effect, but I did end up on the Fougasse page, where I learned there was a British Petroleum Warfare Department in WWII, and read an interesting account of early anti-personnel fougasse usage in the Crimean war.
