Or supply answers which don’t match the questions asked.
What’s your mothers maiden name? %7!%@#
Exactly what I was thinking. Choose a different birthday, for instance. Just so long as you can remember.
Hard to remember.
It's better to come up with a system that will generate replicable results, but will somewhat obscure the answers.
One method might be to run your answers through rot13.
echo Zeugma | rot13

Yeah rot13 isn't a secure encryption mechanism, but it obfuscates your answer enough to defeat some random joe from guessing it.
Alternately, use a hash program to generate a predictable hash.
echo Zeugma | sha1sum

In this case, you can choose the first 8, last 8, or any combination thereof to create a pretty darn good random answer that is yet easily reproducable yet almost completely unguessable.
There are phone apps for hashing text using any of several different hash algorythms.
I'm a nerd, so stuff like this is pretty easy for you, but a little effort expended to obfuscate these kind of answers can go a long way towards ensuring your security from the casual hackers.
