I could anme you so much.
There are for example Nanowar, with Master of Pizza, King, Our Metal is so Strong... etc. Also if you know german, you should try the band JBO, they make some really hilarious songs. They covered Megadeths Symphony of Destruction, and made it to Simphonie der Verstopfung (Symphony of Constipation), and D.I.S.C.O to M.E.T.A.L

Edguy - Save us now

''The sound of explosions, the children awake
The turn of the tide acts up, the ground it starts to quake
A pile of dented steel, in fear I realize
Behind the shuttle's windshield two Evil shinig eyes

Highspeed Alien drum bunny - Highspeed Alien drum bunny

Handcuffed they take the stranded straight into their lab
Examine him, his DNA, what you give is what you will get
He takes his magic carrot, a bang and drums appear
He starts to play like Thunder, mandkind flee to save your hearing


Highspeed Alien drum bunny - Highspeed Alien drum bunny !!

Save us now, somebody - Save us now, someone
From highspeed A.D.B.
Save us now, somebody - Save us now, someone
From highspeed A.D.B.

Bum Bum Bunny B., life is a drag I can tell
But let me count to four and then you play the roll of Hell
One, two, one, two, three, four...''

When in Danger or in doubt,
Run in circles, Scream and shout.

Don't forget Tricycles Of Steel , it's just way to funny.

Haha, yeah, this one's great

"Din din, the bell plays, our ticycles are for gays
Because there's no saddle where our ass lays"
