Help translate this song

[godix]

So my wife started pestering me to make a music video for her. Like a moron, I asked her what song she wanted it to. Now I'm stuck with some jpop song and have no idea in hell what it's about. So can anyone help translate <a href="http://www.animelyrics.com/jpop/megumi/hmbubu.htm">this song</a>? I'm hoping it's all about infidelity which would make the entire 'I did this for my wife' thing rather ironic but somehow I doubt that's it. I suppose I should just consider myself luck she didn't stick me with Celine Dion or something.


For those who morally oppose clicking links, here's the song:
Buusuka Buusuka Buusuka Buusuka
kyou mo genki ni Pyon Pyon de Puu

Bokkari ohisama Nikkomyoko
nanda kao naka ga Kuubekorin
Mifuchi, Micfuchi Raamen Chururin
Shaki Shaki no Kirinpa!

shikkari hyaku KonPiki no Pawaa
ukkari PariPari no Pan! Pan! Pan!
chicchakunatte, gomen nasai
shonbori shichau Shio Shio no Paa
demo, tomodachi iru kara ashita mo hareru kara
Myukki! OK! egao de harikicchaou

Buusuka Buusuka Buusuka Buusuka
yume o mitsukete Pyon Pyon de Puu
Buusuka Buusuka Buusuka Buusuka
Barasa Barasa ni naare

uttori Honyaraka koi shichau
Haato wa DokiDoki doushiyou
Samisa! Samisa! Oneesan ni wa
MeroMero no Tororonchi
tottemo aitai DeroDero no Paa!
furarechau desho ShioShio no Paa
mou! kanashii toki demo onaka ga nacchau yo
Myukki! OK! egao de "itadakimasu!"

Buusuka Buusuka Buusuka Buusuka
kore de genki da Pyon Pyon de Puu
Buusuka Buusuka Buusuka Buusuka
Barasa Barasa ni naare
