Grandpa disguises his books to make them look like they are bibles
This is a brilliant hack. When parents haul their children to church, the kids usually tend to be bored and disengaged, wiggling in their seats. This grandpa keeps his attention by wrapping his favorite novels in duct tape so that the cover looks like he is reading the Bible.
Given that most church bibles are always laminated, this sounds like a brilliant idea. This grandpa could have just laminated it at the store, but he took his time wrapping the books with duct tape (talk about dedication). Imagine reading Twilight while hearing the preacher.
