It happens, also many MANY lead acid batteries explode when you make a connection to them, sometimes spewing acid all over.. ask any technician at a battery replacement center and will give you many examples. There are some cases of Priuses needing expensive repairs after a jump, but I think those were incorrect polarity hookup, a fraction of a second to do damage.
TomT 's advice is good, you can also use a dedicated jumping cord that uses the cigarette plug sockets such as this.. mostly they are used to partially recharge the dead battery:
