You have to say 'what have I got to lose' , find a funny little 1min. monologue or story that showcases your personality.
Other 'monologue' auditions i've done for Uni and Disney are usually pretty easy- you go in 1 at a time, say your short but sweet monologue and they (may) ask you to do it again (slower, faster, with a different voice) and you will find out that day if you get a call back or not.
-Hope this helps
