Beware the Dark Beer!
Found this on the web a while ago and get a chuckle out of it everytime. This lovely knitting project takes eight cans of Guinness to make the helmet. That's perfect since the Black Cans of Guinness Draught come in four and eight packs. I wouldn't try making this after polishing off those eight cans though!!
Here's the link in case, in your dark haze, you convince yourself "oh ya, I can make that!"
