About 10 caravans took over the green near my house last night and I foooooooking hate the gypsy Irish speaking barstewards

It already looks like a land fill site!
Please can we have some suggestions on getting rid of pikeys (if killing/mutilating pikeys was legal that is, and if I was hard enough to take them on

)
I thought torching their cars would be good, but then how would they move their caravans away?
Other suggestions from my mates so far include dropping a few BIG french bangers through the caravann sunroofs in the early hours and also camping out in the trees picking off the young ones with an air rifle
