I love this and wish I could share it with my Dad; we had a thing about aardvarks and at Christmas time made up lots of aardvark carols.
Aardvark herald angels sing was too easy.
There is to this day a plaque hanging in my bathroom. I don't remember if he gave it to me or I gave it to him and it wound up here after he died. It says, "Don't vark too aard."
