"Hyperbole. Learn it. I was making fun of you all. The OP hasn't SEEN Rock of Ages, of course she's leaning toward AQ. Thr simple fact of the matter is that the person she described will enjoy ROA more. It IS possible for some one to prefer hot chicks to puppets, especially someone who has never heard of BWW. This place is so myopic, it's sad."
First of all, for the original poster, Avenue Q has a good-sized fan base on here, so you are going to get many responses in favor of that (which you already have).
I have to agree with Barney Stinson. Based on the person she described, Rock of Ages seems like the most appropriate choice. Of course she is leaning more towards Avenue Q based on her own interests, but if she is trying to make her boyfriend happy, take him to what he may be interested in.
To the original poster: are you surprising your boyfriend? If not, why don't you just ask him what he might prefer? Give him a quick synopsis of each show and direct him to their websites. Let him listen to a couple of sound clips from each musical. I think if you let him have an idea of what he is getting into, you will have an easier time deciding which show to pick. We are not your boyfriend, so our interests aren't necessarily going to align with his.
