So much. I am excellent at lyrics. And a terrible singer. So I sing in my car really loud.
When I was 16 I went to get my driver’s license and found out at the DMV I needed my social security card and didn’t have it. So since then I memorized that, my DL#, my bank account number, and lots of other little numbers like that.
I still speak Hindi/Urdu really well, does that count?
Camp Songs! have lots of them memorized because of my job.
