"I don't understand, Doc," complained Benny Jackson, a man who dedicates his life to trying to impress women, but has yet to succeed.
"What happened this time?" Doc Jim asked as he sat down beside the troubled youth.
"You know Samantha Wilcox? Her father owns several prize horses and has won countless racing medals with them, so Samantha won't look at a guy twice unless he's got a heart bigger for animals than himself. I thought I had my story down right. Will you tell me where I went wrong?"
"Sure, what'd you tell her?"
"A few years back I decided I'd take my mule, Miss Molly, out with me to go gold mining. Several months went by and I found nothing, but I kept looking. One day, I struck the motherlode. It was cold, miserable weather, and Miss Molly wasn't feeling too good. So, instead of gettin' all that gold I found, I stayed with her for weeks. Poor girl was pregnant, and after a few months of waiting and nursing, she gave birth to a healthy baby. I didn't get the gold, I just brought the two home."
"Well, Ben, You're just lucky she didn't throw you out a window with a story like that!"

What was Benny's mistake?
