This may or may not be apocryphal but I still like the story of the large american twin jet that had an engine failure off 27R at LHR. He called to ATC with something like "Climbing straight ahead and dumping."
ATC now in a spin as that meant the twin would dump fuel all over Windsor Castle with HM in residence so ATC advised twin jet accordingly and asked them not to dump.
The reply from the twin?
"Sir, does she want some of it or all of it?"
Moral of the story?
As Rhino says. If you really need to lose it - let it go!
