Birds that are not so happy

I'm sure most of you have seen the
trailers of Angry Birds somewhere sometime ago,
but well,
for the benefits of kuku people like me,
who watched it only like last week
and find it interesting enough,
i shall leave the videos below for your viewing.
It all started of me asking my younger sister some idiot questions
of why the angry birds are angry that i found out from her
that there is actually a video that explains why.
Haha, and here is it.
Enjoy. =)







And there are many many more that can be found at youtube.
