How was school today bug?
"It was good, but Mrs. Parvin wasn't there because her son was sick."
Oh that's too bad, who was your teacher since she wasn't there.
"Well it was Mrs. Lisa and Mrs. Katie.......and Mrs. Bustitute."
"Yeah Mrs. Bustitute!"
Mrs. Bus-ti-tute.....do you mean Mrs. Substitute?
"Oh yeah, that's it!"
