I am very sorry to say I laughed through this scene.
Not because of the what was happening per se, but because I was watching this straight on from the previous episode, in which Mr. "This has been passed down the family line for generations!" Armstrong was introduced.
...so of course, as soon as I saw Armstrong blubbering in the background, "This method of blubbering has been passed down the armstrong line for generations!" went through my mind and I dissolved into giggles.
