Consider this excerpt from "Ernest T. Bass Joins the Army."
Andy to Army Recruiter: "A while back he was going with a girl up here in the mountains...she married somebody else and he got mad at 'em and took rocks and busted every window in the house."
Barney: "He even kidnapped the girl..."
This is an obvious reference to "The Mountain Wedding." I'm sure you remember who really got kidnapped. Also, does anyone remember any reference to Ernest T. and Charlene ever actually "going together?"Also, it is interesting to note both episodes were written by Jim Fritzell and Everett Greenbaum.
