My first one looked like that as well. if you have not used it, and have a desire to make it look prettier, do it before you use it. The constant heating/cooling on them tends to make them a bit more rigid.
You don't need a corny, if you have a co2 tank or even a bucket you can have your girlfriend grab one end and you the other, forming it around the bucket. Or, you can go to a 7-11, or gas station, and tighten it around one of those concrete poles that are supposed to stop cars from driving into pumps or what not. You might get weird stares/arrested, but hey whats lift without embarrasing risk?
