Granted, you know that you should travel back in time and specify exactly what you meant when you wished for a chili dog, and also find a way to phrase the wish so it has no negative repercussions, however you are unable to travel back in time to do so, so you are still stuck with a chili-covered dachshund which has begun to shit all over your room.
I wish I could travel back in time and go to a Led Zeppelin concert, performed by all the original members of Led Zeppelin, and not get raped, mauled, molested, violated, killed, beaten, drugged, or harmed in any other way at the concert. Front row seats would be nice as well.
