"That's How Much I Love You" is a country music song written by Arnold, Fowler, and Hall, sung by Eddy Arnold, and released in 1946 on the RCA Victor label (catalog no. 20-1948-A). In October 1946, it reached No. 2 on the Billboard folk chart. It was also ranked as the No. 10 record on the Billboard 1946 year-end folk juke box chart.
The lyrics attempt to quantify the singer's love for his girl. If he had a nickel, he would spent it all on candy for her. If she was a kitten, he'd stroke her and listen to her purr. If she were a horsefly and he were a horse, he would let her bite him. And if she wanted to marry, he would find the parson and let him tie the knot. The song closes: "That's how much I love you."
