Does anyone know of a good way to stretch out on fly jeans?

I'm sitting on the computer with my jeans on trying to stretch them out. I can't do the hanger trick because their on fly. Since moving to Texas, I'm no longer a size 4. (Great Tex-Mex Food!) Please help before I explode. Buying a new pair before I go out tonight isn't an option. Please be kind, I'm trying to lose the extra pounds. I got the three out of 5 ons, so far. Wish me luck, or at least help scrap me off the wall, when I blow up!
