"Cowgirl" by William Robert Duke

Mark McKane: Hey Paw! Whats that?
Lukas McKane: Thats a Cowgirl Son.
Mark McKane: How did we get one of those?
Lukas McKane: Well Son, remember when that falling star fell in the east pasture?
Mark McKane: Yeah and the grass grew real funny like there.
Lukas McKane: Now you know why.
Mark McKane: What do we do with it um her?
Lukas McKane: Well Mark, you will do your chores and homework and I will "talk" to this cowgirl.
Mark McKane: Aww Paw!
Lukas McKane: Well, you know I have been a mite lonely since Lou Mallory left for Oklahoma city...
Mark McKane: Ok Paw!
*Lukas McKane takes the cowgirl by the hand and they walk into the house*

Hope they don't sue me for revealing the plot for Rifleman 2050 episode 303. Great job with this.
