In episode #141, "Samantha's Wedding Present," Endora shrinks Darrin to a miniature size. As he slowly shrinks, Larry notices how much taller he is than Darrin. So, Larry asks Darrin how tall he is. Darrin replies 6'1". Larry says that he, also, is 6'1". Well, if you check any other episode where Darrin is normal size, you can clearly see that Larry Tate/David White is several inches taller than Darrin Stephens/Dick York!
Has anyone else noticed this. I discovered it years ago.

Yes, I've noticed this. Although I think Dick York really was 6'1" (but I'm not completely sure.) And David White must have been taller than him, but it seems that in this episode Darrin is shorter than usual in that scene. Wonder why... http://www.sitcomsonline.com/ubb/tongue.gif
