My hypothetical scenario is, you have two pilots, an 82 year old and a 23 year old, they got to talking about LOP/ROP operations. The young one, who is up on all the latest knowledge, is pulling the mixture back to LOP. The old guy, set in his ways, exclaims "you'll blow the engines up!, Fuels cheap! Run it ROP!" A scuffle ensues and the young pilot knocks the old pilots hand away, causing the mixture to go to Idle Cut Off. The old pilot not trusting the young pilot to handle asymmetric operations tries to grab the controls. Young pilot clobbers old pilot and conducts a forced landing.
(Disclaimer: I was not there, I have never met the people involved, I've never flown a twin, I mean no disrespect, I do not work for CASA, I'm not a LAME, I'm not a CPL or ATPL etc. etc.)
