Building a time machine to stop Hitler

I am building a time machine to go back and stop Hitler. Please be part of this noble cause....history will remember you as a hero. Also, if it works out and you donated I'll come back to the present and send you to any year you want to go, including the prehistoric era so you can live out your Jurassic park fantasies or be the person who discovered fire. Also, I can make your dad pull out if you want.
