Replying to Egging Trucks

So my parents brought down their truck to let me use to come home from school after my last exam. Since it was a snowstorm and the roads were bad i decided to stay and party for a night and leave first thing in the morning. Well i woke up this morning to find my truck was egged, and a shopping cart in the back of it. For those who dont know egg removes paint from vechiles. So now i need to get it washed off asap and then tell my parents what happened as it might need a new paint job or at least paint touch ups.
