Glad to get a 4 today. Not doing so hot in my league but having fun :)
1) :) Lithograph. Spent a lot of time thinking about the etymology and happy I pulled it off
2) :( Wolf. Whoa... weird we all guessed this.
3) :) Mark Twain. Happy to have pulled this off too
4) :( Cassandra. Knew this was wrong but never would have gotten this. Was thinking it was a long name.
5) :) Beavis and Butthead. Heh heh.
6) :) Solstice. Seemed pretty easy
