Double entendres

I'm doing a very very short talk at church on Sunday night. It's on the theme of love because it's near Valentine's day. Given the theme, the day, and the fact that it's informal worship, I have this fear that I'll accidentally say some kind of hideous double-entendre. One badly constructed throw-away comment, and it could descend into a ribald discussion of the ordinand's love life. And then someone will record it on their mobile... and send it to my principal... and then I'll get expelled for inappropriateness in the pulpit...
