Powerpoint presentation help!?

Ok. I am doing a powerpoint presentation with 10 slides and the first slide is a sentence that introduces the presentation. A music intro starts and the topic of the slide pops up. The next slide, I have a paragraph that I want to come in reversed and then flip flop to normal. For example, "doT dias taht eht rac saw tuo fo epahs," and reverse to "Tod said that the car was out of shape." Any idea how to do this? I have Powerpoint 2007.
