It's a good idea to be playful about your occupation IF YOU JUST MET WITHOUT ANYONE COMFORT BUILDING. She has to qualify herself to be worthy to hear what you do for a living. Don't give up to much information too fast.

Early on in set
Her: So what do you do for a living?

You: I invented the speedo.

Her: Psh, ya right!

You: It's true. Every time you see a fat dude walking around and showing too much skin, you can send me a little thank you note.

Later on in set, after you have fluffed her and built comfort:
Her: So what do you do for a living?

You: Right now, I'm a student, but I REALLY want to be a Hollywood actor/model!

Her: Wow. Really?!

You: Ya. It's definitely a big pair of shoes to fill, but I have this uncanny nac to believe in myself and accomplish my goals no matter what the odds are against me.
