How Scrabble is ruining my normal person life

I was placing a telephone order and the customer service representative asked me to read the order number to her. The number was a sequence of letters and numbers which started with NAK, so I started off really easily "N as in Nancy, A as in Apple," then it got crazy "K as in...Kop...Kue...Koa?" Finally I just said "K as in Kay!" Oh man. Yes, someone has been studying her short Kay words. Even now I can't think of a normal word that starts with K, oh kitten! oof.
