Stone-cold killer after my snarky Grandpa

Do you have a snarky, conniving, wily grandpa who speaks before he thinks. An upbeat grandpa that everyone tries to outwit and yet he's unbeatable. Do you wish a stone-cold killer would take him out? OF COURSE NOT! His wife, daughters, and grandchildren will stop at nothing to keep their grandpa. Normally Grandpa's very capable to handle anything but he's in the middle of an existential life crisis of his own making. With this story, I might wring every emotion out of your body, in a tasteful, forceful way. A heartwarming, frustrating, and hilarious romp of life that'll throw you on your butt. Grandpa is like Tom Sawyer, but bigger. Stay away from this book if you don't have a sense of humor or have never laughed at yourself. I mean it.
