The elephant skit was hilarous.
To me, his funniest was Tim as the Dentist and Harvey Korman as the patient.
The original skit was in 1969 and redone on the later Burnett series. Most of the online videos are of that later version. The original was a bit better, but apparently that video has been lost, as, I think it was in black&white.
Color version of Dentist Tim and Patient Harvey:
I can’t watch that. It’s my husband’s favorite, and I laugh till I’m in pain every time he runs it on the Roku ;-)
