What types of things should a good jazz dance combination include?

i just quit dancing after 12 years at one school and for this upcoming summer i need to submit an audition tape with a jazz combination and a jump and turn combination... whenever i try to make anything new up all the old stuff comes right back into my head.. what are some ways to create an advanced jazz combination???|||Oh, a few pirouettes and plies. Why don't you watch some dance videos on youtube.com and just get some inspiration and use it as a starting point.
