living in delaware, I don’t have access to many cows or pigs. I do however have leads on a couple of senior pranks.
the engineering students at UBC (the university of british columbia) yearly have the best senior pranks. on their campus, they have a huge clock tower. on this one particular night, everyone went to bed as usual. the next morning they all woke up to find a volkswagen bug (one of the vintage) affixed wheels in towards the clockface. not just held there by ropes or cables, this thing was welded on. the kicker part is is that the clocktower is about a hundred and fifty feet tall. the closest crane that big was three hundred and fourty miles away, on the site of a new library being built (by the state, and being as UBC is a state university, they’re not too likely to volunteer their crane to deface their own property).
The next year, also at UBC, a volkswagen bug ended up on the underside of the bridge connecting the engineering campus to the rest of UBC. the bridge is a hundred feet above water that is another seventy feet deep. the bridge spans across the river a collosal 500 feet, and the car was stuck smack in the middle of the bridge. no crane would be accessible to get at that angle at that spot. the car in this case was wheels up as it was affixed to the bottom of the bridge.
more locally, a group of high school students caulked their entranceway closed at school (a glass one, with double doors inside) filled it with water and put fish from a nearby pond into it.
I think that’s enough to satisfy your interests for now
