Ween were never meant to be taken seriously. They're all proficient musicians and can handle any genre put together. Even their more serious albums, like Quebec, have humorous songs (It's Gonna Be a Long Night, Zoloft, So Many People in the Neighborhood). They're a weird case because they're beloved by jam band enthusiasts as well as your smarter music fans. They're divisive, you either get them or you don't, but they were one of the best live bands around, saw them about four times and the were awesome and played for about three hours each time.
