I can imagine the good laughs, you would have to get him a mug with number one Dad I won that says carry on buying

Every few months and watch the mount up in his cupboards to see if it lead to changes

Maybe just give stuff away to friends if you don't want to sell the stuff one man/woman grap his another man/woman treasure

Anyway sooner or later you will win or the junk will win, one will break eventually

On a side not I am looking forward to one day getting my best dad mug or new father mug as well as the classic slippers as well

And the Scrooge hat
