An anime family runs into a house, causing the house to stretch like elastic. What the heck is going on inside? Surely, they're knocking about inside, but how exactly? Here's a theory.
Anime shows come and go, but there are two animated programs that are bound to be shown on Japanese television forever: Doraemon and Sazae-san. Broadcasted since 1969, Sazae-san is a show that, at one point or another, pretty much every Japanese person has seen. These days, the show is seen as like an animated Leave It To Beaver of sorts -- good wholesome entertainment for the whole family.
The above GIF shows a segment from the closing credits. On 2ch, Japan's largest forum, one net user has a theory about what is going on inside the house. Have a look:
Now, here the image is slowed down.
And in colour, which might make it easier to track the chaos.
Once again, slowed down.
Since this has been pointed out, I now do wonder if the family is running into each other, causing them to bounce about like rubber balls with the lead character Sazae-san getting stuck in the chimney.
