(Last Lines in series)
Mr. Ed: Hi Wilbur!
Wilbur: And where have you been all night?
Mr. Ed: Making house calls.
Wilbur: House calls?
Mr. Ed: Yeah. Since you closed my clinic, I've become an old fashioned horse-and-buggy doctor.
Wilbur: (Wilbur's very last line) Well, Ed, I'll say one thing. You're the buggiest horse doctor that ever lived.
Mr. Ed: (Mr. Ed's very last line) Aww shucks.
