You can't, I already volunteered, one way if necessary.
Its bad enought to put up with you here, but on Mars! Gimmi a break!
I actually have volunteered to go to Mars - one way if necessary - several times. And I've volunteered for other assorted space missions. They have ignored me for too long!!! I'm starting a write in campaign. SEND FURBALL TO MARS!!!!!
And I don't want you interfering with my hot dog stand once I'm there, either. Harumpf.
