I think this is a really funny episode.
Reba having to work for Barbara Jean is hilarious.
Barbara Jean is her usual crazy self, and she tries to teach Reba to be her assistant ("Welcome to the dental office of Dr. Brock Ha-art. To syllables in "Hart". Come on, sing it with me, Ha-art.")
And Reba getting dragged into Brock and Barbara Jeans marriage, when Barbara Jean complaints that she and Brock haven't had "intimacies" in over a month and asks Reba for advice.
With Cheyenne starting college, Van has to stay home to watch Elizabeth. It so funny when he's using a stopwatch to practise changing a diaper fast.
