Suggest risky interview tips

Hey,

I have an off-cycle interview scheduled next week at a really small boutique for an internship that lasts 4 months, which is non negotiable.

Now, I am only available for 3 months so I know I won't get an offer and I am using this as a practice interview. Any tips on risky or unusual strategies to impress the interviewer while staying respectful ? I'm open to your thoughts since I've got nothing to lose.

Cheers
