If you're prone to wailing on things that aren't doing things that they should (damn, I could show my chauvinistic side here) whack on the starter while someone tries to start the van. Just stay clear of anything that can grab ya when it starts, unless you really need the feeling of companionship....
I'm sure you're mature enough to remember Andy Griffith saying "Just spit in the back and give it a whack, that's what my daddy always did to get our ol' radio working."
