Tegan & Sara tell the best jokes.
I've always thought of The Donnas as good, dumb, and fun. I guess they've sort of evolved with the last record, but I like the heyday of them singing and playing sloppily about boys and hot dogs. They put on a good show. Very contrived and rehearsed, but funny because of being so contrived and rehearsed. I saw them in 2000 or so, and they told the same exact jokes at the 3 shows I went to.
