I didn't laugh at all when I saw it first,...
but watching it this 2nd time, I let out a couple of chuckles.
However, I don't think that makes it worth watching. Sorry.
I feel the voices throughout are a bit too quiet and the music - when it exists - drowns them out a bit.
Also, why is there only music right at the start and end?
It seems that some love this, so well done. I found it amusing for a few seconds, but I suppose it's just not my kind of humour.
Having said that, I laughed really hard a while ago when a friend dubbed an advert on TV... Hmmm...
Maybe if you tried to form some sort of shitty story it'd be funnier?
