Hunt them down, and kill them......
Thats the spirit! HOOOAH!
Jona, it sounds as though those guys did that to you on purpose hoping that you would C###P your self.
Keep your eyes open! I'm just glad that they didnt succede in rattling your nerves, they must of spotted you ahead of them and they just decided to have fun at your risk and expense, Now that is truly a pair of A holes. maybe next time if you see them comming and you just happenm to have a bag full of marbles and quart of oil in your back pocket you could return the favor by spilling it ahead of them and make it interesting for them!
