Who am I?

Mingle speaking activity in a group.
A label with the name of a profession is attached to your back.
You will walk around and ask questions about your profession to guess who you are, 

i.e. Do I work outside? Do I work with other people? Do you have to be strong?
If necessary, some smaller comments can be added to Yes/No-answers, but not telling the word itself. 

Here I am- a drug dealer...
who would have guessed that could be my job ? haahaaa!
