Towing Issues: im stupid so my car is stuck, garden ditch, mom and dad

Question
I was wondering how to get my car out of my back yard. Ok I'm 17 and i had got my car keys taken because my mom and dad was scared for me to drive as they go out of town for 8 days on vacation. i wanted to go somewhere and my mom and dad cars was parked behind mine. so my sister said nobody was next door and advised me to drive across the grass to pull out her driveway (note that it's snow out on the ground). I knew the car would make it if you maintain speed through the grass. but i noticed there was a car and i got stupid and stopped. bad move i know. so i was wondering how can i get my car out. its FF drivetrain and the front wheels are freely floating over a little garden ditch in are yard. how can i get traction on those wheels to pull it out the backyard. i also already got in trouble so it's not that I'm in a rush.

Answer
well after I picked my self up off the floor from laughing so hard.  I really do not know what to say other than I guess paying for a tow truck will be the choice..

Even if you had someone come with another vehicle and try to pull you out then it could cause more damage to the yard.

Sorry, its hard to really answer this question other than that way.
