Years ago my bike was locked up outside Crawley college. When I came out and tried to undo it, it was completely seized.
I called my brother who brought some bolt cutters out, but these barely scratched my Kryptonite d-lock.
We ended up at the local fire station and asked them if they had something I could borrow. They offered to come out and give me a hand, so we went back to my bike and waited, expecting a smallish support vehicle to turn up.
After about 10 minutes, a full-size fire appliance turned up, fully loaded. They proceeded to use the hydraulic car-opening cutters and managed to break the lock. I thanked them and we went our separate ways.
True story, bro.
