Possible title of book seven?

"I am currently trying to decide between two possible titles. I was quite happy with one of them until the other one struck me while I was taking a shower
in New York. They would both be appropriate, so I think I'll have to wait until I'm further into the book to decide which one works best."
Struck her in the shower?
Is that a clue?
How about 
Harry Potter and the Frog Spawn Soap.
