One of the running gags in Priscilla's Pop involved Priscilla continually asking her pop to buy her a horse, and of course he always refused. Naturally, since her father was unwilling to get her one, she would also ask Santa Claus to bring her a horse every Christmas as well. This, of course, never happened, but as we can see here she went to every length necessary to ensure she would get one.

There's a kind of interesting kid logic going on here. It's true that it would be difficult to get a horse down a chimney, so it would make sense for Santa to bring it through the door instead. However, it seems that Priscilla thinks that the reason why Santa uses the chimney in the first place is because he doesn't have the ability to open doors himself, which is why she opened it for him. I wonder how she thinks he gets in and out of his own house. Maybe in her mind there's just a bunch of chimneys, and no doors. That would be interesting to see.
