mom on the phone

[mom] You had how many hot dogs?
[me] Six. Six in six hours.
[mom] Well, geez louise! How come you did that?
[me] Oh, just to do it.
[mom] Well, it's a good thing you've had your appendix out!
[me] Why do you think all those hot dogs would give me appendicitis?
[mom] Well, when your father and I lived in Chicago he once ate ten hot dogs for lunch and it made his appendix burst.
