Takeoff briefing for multi-engine aircraft

I'm working on my CMEL and MEI right now and every time before engine start when I give my passenger briefing I get stumped. As a CFII with dual given experience I'm comfortable with a passenger briefing in most cessna and piper aircraft. Though in the Seminole (PA-44) I get continually get stumped (it might just be the nerves of adding an extra engine). Does anyone have a good way to remember items on a passenger briefing? Maybe an acronym?

Thanks for the help!
