Yeah, what ARE they for?

While I was reading comments on posts on my family genealogy blog:

Rhett, looking over my shoulder: Wow, do people really read your blog?
Me: Apparently a couple actually do.
Rhett: I mean, I know I read it--
Me: You do?
Rhett: Of course. What are boyfriends for, if not to read your genealogy blog?

(Compare to Suellen's attitude here.)
