You should also check out the Livejournal community "Bad eyebrows". I go there when I'm need of a good laugh. In my opinion, aside from the standard unplucked bushy eyebrow, there are two kinds of bad eyebrows: the line and the sperm/McDonalds eyebrows. Both types are over-plucked and are spaced out far too much like Betty Boop's.
