Yokes or Jokes

Nicholas is so cute! When I was packing our bags this morning, he saw me put some hard boiled eggs in his daddy's bag and said he wanted one. I showed him how you crack the egg and peel off the shell and rinse it off. We got in the car and he started eating it. After a few minutes, he finally got a bite of the egg yolk and spit it out, wiping his mouth on his sleeves (of course). He told me was sour and that he didn't like it. He then told us that Miss Doris (his teacher) gives her "jokes" to Miss Rachael (another teacher). It was so funny! He kept saying, "Miss Doris doesn't like jokes, but Miss Rachel likes jokes", and "Miss Doris gives Miss Rachel all of her jokes". I tried to tell him that it was called a yolk, not joke, but he kept calling the yolk a joke.
