At the end of the working day

At the end of the working day, you dropped by Samantha's office and asked "Care to explain?".
"Yes, but not here!".

An hour later you were sitting with 'Samantha' in a cheap motel room...
"See, and with this I can make myself look and sound like anybody and anything else!" Walter as Samantha concluded in his male masculine voice.
"Okay! Could you please show me?" you asked.
"I don't know, what did you have in mind?" came Walter's question.
