I noticed something on my Season 3 DVD that I hadn't noticed before which is kind of surprising since I have watched my DVD so many times. What I noticed is the episode Tony's Wife when Jeannie is in the kitchen checking on the dinner and she takes the turkey out of the oven to check it, she suspends pot of turkey in mid air but when she does so it appears that she twitches her nose instead of blinks. The reason I say this is because when she blinks to make something happen she squints her eyes but in this scene her eyes were open and it looks like she crinkles or wiggles her nose to suspend the turkey in midair.
I might be wrong but that is what it looked like to me. If anyone could help me out on this I would appreciate it.

She sometimes scrunched her nose a little up, but it never twitched - to my knowledge.
