Why "Does a Cat Got an Ass?"?

You may be wondering how I came up with the title "Does a Cat Got an Ass?".  I first heard the expression about five years ago when I asked a new aquaintence, an 81 year old ex sailor, if he wanted a glass of iced tea. "Does a cat got an ass?", he replied.  I burst out laughing, hysterically.
Since then, I have gotten to know Melvin quite well. He's 86 now, but he still keeps me in stitches with the sayings and the stories he comes up with.
One day a mouse went running across the floor of his kitchen. I screamed, and Melvin opened one of the cupboard drawers. He pulled out a pack of bamboo skewers (the kind you use for shish kabobs)and proclaimed "a few more of those (mice), and some "Three Horse Beer" and we'll be eatin' good tonight".
On another occasion, I was helping him with a bit of cleaning around the house, and he stopped me in my tracks and said " why, you're as busy as a cat trying to take a shit on a tin roof!". Oh how I laughed at that one!!
Anyways... there are a whole lot more, but for lack of time, I need to end this now. I will, in the future, be sure and include more "from the mouth of Melvin", for your entertainment.
