What is a good name for my band?

I really like Watch out Penguin! because it's unusual. When finding a band name, you want something that stands out from the rest (but from your list, I'm thinking you know that). I know someone else said The Dropouts, but that one sounds too cliche to me. Personally, I like Watch out Penguin! and Post Nostalgia best. You might want to consider The Men Who Stare at Guitars for a CD title, though, cause that one's brilliant. All in all, good list, and good luck with your band!
