"Oh B.D.! So many fun times with you and Lou! We have been laughing about many of the times we shared together.Chocolate martinis and lobster tails one of our fave nights, “here’s your ham”, “drink this horrible shot if you’re hungover! Just drink it! Why did you drink so much?” You were right, I was cured instantly!, “Overpay your mortgage!” and my one of my all-time faves, “Just use gasoline!” to light the grill or fire pit, burning the dead Christmas tree, clean up something in the driveway, get something off your hands, and the list goes on!I hope you wore your green pants and your AA sweater through the pearly of gates of heaven! You will be missed, and we will check on Lou. Curt and Kelly"
