Where do you guys listen to Steve Martin?

Ok let me explain what I am looking for in particular as I was interested in listening to his comedy because I once heard that comics like Louis CK were heavily influenced by his style such as the naming bit, and I wanted to see how that joke originated.

However, while I did try using YouTube to find that particular bit, I couldn't find it again regarding the bit where Steve Martin talks about naming kids as I know that is one of his most famous bits, but I wasn't sure where to find the original video itself.
