Klackner can get some use out of it

"Oh, I definitely can get some use out of it!" Klaus said. And added "But I will need to run it with my superior, Mr Martens first! Also, could you please change back? It is kind of unsettling to be talking to you like this!".

"Alright, here we go!" Walter said as she stood up and started to undress.

"Wait, what are you doing?" Klaus asked.

"I am undressing! That is a prerequisite for changing back because of the way the device works!" Walter said as the first part of her clothes came off.

"Well, there is that! Was a hard task to put that on in the first place!" she said as she sat down to pull off the rest.

"I can only imagine..." the 40 year old police commissioner brought out.

"Klaus, why are you so shy? Have you never seen a naked woman?" Walter continued.

"Yes, but not one who talks in a male voice and claims to be my best friend!" Klackner responded.

"Well, don't be so uptight about it! Also we will have to demonstrate the device to your superior somehow!" Walter went on.

"Gosh, you are right! Any ideas on how to do so?" Klackner asked.

"Hmm..." was Walter's only reply.
