I think it was Peacebang, or maybe it was someone quoting PB. In any case, whomever you are, thank you. I preached this Sunday (all about forgiving God, forgiving others, forgiving yourself) and used the trick of sliding pages over, rather than flipping them.
Eureka! Don't you love it when something so simple, so easy, is so revolutionary?
Mwah, mwah, dahlings.
