"Yakety Yak" by The Coasters (?Is this right? I don't own the song anywayz!)
"..." sang by...the scientists...?

Take out the Leos and them Oz
Or you don't get no mission next
If you don't scrub that Gundam clean
You ain't gonna fight and make a scene
Yakety yak (don't talk back)

Just finish fixin' up your leg
Let's see that detonator blast
Get all those Aries out of sight
Or you don't go out Friday night
Yakety yak (don't talk back)

You bring along your guns and bombs
And walk yourself to destroy Oz base
And when you finish doin' that
Gundam's broken so you just fix that
Yakety yak (don't talk back)

Don't you give me no dirty looks
This scientist knows what to do
Just tell your baka friend outside
You ain't got time to take a ride
Yakety yak (don't talk back)

Yakety yak, yakety yak
Yakety yak, yakety yak
Yakety yak, yakety yak

FADE

Yakety yak, yakety yak
