At the time I had a strong disdain for jQuery, preferring instead to write my own raw JavaScript or use a library more oriented towards extending JavaScript than DOM traversal, so I replied "I hate jQuery." It got a good laugh from everyone. When prompted, I proceeded to explain my reasoning on why something like MooTools or Prototype or YUI might be better. Ironically, I ended up using (and loving) jQuery a lot during the course of the project, as extending JavaScript wasn't something that was needed for the project (it was UI-heavy).
