Anyone notice that Nora almost laughed

[toodlepip]

Have a look at the two anniversary shows with their outtakes, you can hear the crew laughing there as well, especially with Bill Owen´s umbrella and the "flat lady" ;D.

 

[Who Is That Then]

I just viewed those 2 episodes mentioned here. Seems when Ivy would hit Sid in the chest with her hand is when she seemed to be supressing a smile. And at one point as she sits at the restaurant table in the background she seems to be slightly smiling. But she at no point out and out laughs or even fully smiles. She had good control and had her mad act down pat.
