"On Top of Mount Fuji" joke

Sing this to the tune of "On top of old oaky from "That's so Raven".
On top of Mount Fuji,
All covered in blood,
I shot poor Barney
With a 45 stud.
He went to the hospital.
He wasn't quite dead.
So I took a machine gun,
And blew off his head
I went to his funeral.
I went to his grave.
Some people threw flowers,
But i threw a grenade
TaDa!
