I've seen something like this before, if you are lucky, then it was a purpose break designed to limit the amount of damage done to the body lens and would only be a few hundreds to fix.
If not, then that sucks mate, i love goofing off, but not with couple grand of equipment. You buy one of those LensCups for that ^.^
Seeing the face of a friend as you send his 70-200 flying through the air is priceless.
Rental houses love it too, "Here i brought back the lens, CATCH".
