A Sears 'Die Hard' battery video, complete with 80's nostalgia music:
I know, I know; the electron-heads out there will point out that it proves nothing really about the battery - the amperage draw never gets close to the battery's rated capacity, and once the first car starts it's alternator helps start the next, meaning the load drawn from the battery decreases accordingly. This is true.
This is also the reason engineers are no fun at parties.
