How about Lemonjello ("Le'mon'jelow")
Snopes doesn't necessarily say, I would hope they weren't used but who knows?

Orangello and Lemongello are urban myths. If anyone personally knows folks with these names, I'd love to hear it.
I don't know if it's true or not, but I had a conversation with a guidance counselor years ago that claimed that one of her students had given a child this name.
