Just go with the snark and out in a joke answer that you will find funny. Some of my security questions are hilariously inapplicable, so the first silly, snarky thing I think up is likely to be memorable. It is also a little hard to guess unless you know me really well to an unlikely degree, and it won't stick out as much as a sore thumb in multi-choice situations.
