"Senior" holds no weight with me. I've had plenty dumb founding conversations with "seniors".

My favorite was at the company that was self hosting their code. The senior team lead wanted me to help him find a memory leak that plagued the product for months. Customers were told to restart the application every few weeks (this was a C++ application).

I sat down with the senior and looked at the code. I spotted the error.

I was like, "You know when you do new[] you need to use delete[]?" as all of his deletions were without [].

The look on his face was the best.
