I don't care what your name is, Fat Boy..
I don't care what your name is, Fat Boy, get your reindeer off my roof!
Before anyone takes offense, every Christmas when I was grown and living far from my "folks", we would either call them on the phone or drive home for a visit.....and the first thing I said to my Father, either over the phone, or as we get out of the car to greet them, was the above.
He was significantly overweight, but he was very comfortable in his skin, and we all had a good laugh.
I miss him, especially at Christmas time.
