My Father Killed a Kangaroo

Tune: Terre de Nos Aieux

My father killed a kangaroo,
Gave me the grizz-el-ey part to chew.
Wasn't that a terrible thing to do,
To give to chew the grizz-el-ey part of a dead kangaroo.

My father killed a parakeet,
Gave me the teeniest feet to eat.
Wasn't that a terrible feat to beat,
To give to eat the teeniest feet of a dead parakeet.

My father killed a grizzly bear,
Gave me the hairiest part to wear.
Wasn't that a terrible fare to bear,
To give to wear the hairiest part of a dead grizzly bear.

A round, but one that goes on to a second and third verse, 
sort of a spiral.  From Joe Hickerson, I think.
