I'm also remembering that some of the episodes that I didn't think were my favorites are really very funny. I just watched "Marry Me, Jennifer" with Hoyt Axton. Starting with his song to Johnny about having a knife and a gun and having a little fun, to the random guy in the elevator getting sucked into the situation to Johnny yelling "chips are falling!"
My husband and I still yell "Chips are falling!" when random bad-not-terrible stuff is happening.
And, as someone else mentioned above, both my hubby and I went into radio (he stayed) in large part due to WKRP. He's now an Andy Travis at a very successful station.
