Yes, Roast Mules....I was just reading a post about remaining child like as we age and it reminded me of this.
It was in a book I was reading years ago, actually on New Year's Eve 1999. We had kids, so we stayed home to celebrate and tried to figure out this puzzle.
When you rearrange the two words, it becomes one word. A simple word that any child would use.
Have fun with it....if you read this blog!
