While it broke years ago when I was stationed at MSO Portland OR, my still favorite coffee mug had a drawing of the most mournful looking hound dog you ever did see, and the caption: "Smile, later today you won't feel like it."
Currently, I'm using the one my sister sent me a couple of years back, John Wayne on one side, an the quote from one (or more?) of his movies: "A Man's Got To Do What A Man's Got To Do."
30 years with this mug. Use it all the time not just Christmas. I'm not sure what I like about it other than many happy family memories. This is actually my just in case of breakage duplicate I found a few years ago on eBay.
One my son had custom made as a gift for me. He had a pic of he and me on a boat with the Skelligs of Ireland behind us. I took him to Ireland after he pulled a 4.0 his first year in college. Father son trip to castles and pubs. Sweet memories
