HELP!! CAR STUCK IN MUD!! HELP!!?

Okay! I was listening to my grandmother and she told me to park my car in the yard because if I park it on the street someone will hit it. So being the obedient granddaughter I am I did. Well long story short I parked t in the yard today in the car got extremely stuck in mud! And I cant get it out. And Im so freaking right now because I got work in the AM. Can anybody give me any ideas on how to get it out! And will this mess up my vehicle in any way? Thanks in advance!!
