Two truths and a lie

Last week-end, I attended a strategic planning meeting for the Autism Society, and a group of us went to dinner after Saturday's sessions. We played a game where each person would tell two truths and one lie about himself or herself. The others were asked to identify the lie. My three assertions:

1. One time, I yelled at Lucky Reagan--the late President and Mrs. Reagan's dog--to "Shut up!" when it was barking.
2. Due to a volcanic eruption that grounded all incoming and outgoing flights, I had to stay an extra six days in Iceland.
3. When trying to join a tall club, I failed the measure-in.

Any guesses as to which one is false? Nobody got it right at the dinner!
