I'll be honest, it sounds just as unlikely that he said "McNeil" as it does some variation of the "n word".
I don't hear either.
I hear clearly "Gimme one a nem nurr." = them there
I suppose, especially since he claims himself to have said it, I can hear "Gimme one McNeal", with McNeal pronounced more like "McNurr".
I imagine he doesn't even really remember saying it exactly, but knows he didn't say "that".
Again for review:
