Counting One, Two, Three

B: I don't want immunization shots!
Boss: You know, Dad and I had these shots when we were kids.
B: (Howling and kicking)

Boss: Shots hurt but you know you have to get them. Relax and it would end quickly and hurt less. Here is a trick, calmly count "one", "two", "three" and it would be finished.

--
B: Wow! I counted "one" and "two" and, before I could count "three", it was over already!
