Has anything like this been done before?
A man enters a wine shop and trys the sample wines. The shop assistant tries the wines with him as well. The wine assistant is obviously getting turned on by the taste of the wine. He starts off with little comments such as "Imagine having this with a nice steak, mmmm", but soon leads on to comments such as "I'm getting (sniffs) Yes (sniffs) I'm definitely getting some wood".
Something similar happened to me today and I thought it was quite funny. Translating real life into comedy doesn't always work, but with some exaggeration, perhaps this could.
