I lied in a job interview and said that the yodeling walmart boy was my cousin
Seems silly, why lie about that?
The interviewer asked me if I knew who the walmart yodeling guy was and it sounded like they were asking if I was related to him so I lied.
Well they are going to find out the truth at some point. You might not get the job if they find out that you lied in the interview.
I don't care if they hire me anyways, I don't plan on staying there long
Regardless of whether you plan on staying there for a while, you still shouldn't lie at job interviews, or in general really.  Eventually that habit is going to get you in trouble if it continues.
