Just a gentle suggestion.
Your guests may wonder why you keep cake in your shower. Let's just hope they don't try to eat it.
Let's face it, soap will end up covered in bacteria anyway, why not give it a head start?
Is your bathroom trash heap themed? Do you collect stray cats and old food remnants? Boy do I have a bar of soap for you!
If only prescription chill pills would bathe you and make you clean as well as making you happy.
I hope these soaps come with a flavor map in the box because if I start using one and discover it's coconut inside, I'm throwing it right over the shower curtain.
