Boy, those preachers really must have dirty minds. Or is it our dirty minds? These suggestive reader board church signs weren't meant to be inappropriate (except for maybe the last one), but we can't read them without giggling. "Open your mouth and I will fill it?" Who writes this stuff? (OK, fine, it's written in the Bible. But does it need to be on a public marquee?) The gallery above contains the Internet's best dirty church signs, and our laughter has seriously brought us to our knees. In a respectable way, of course.
