Motherfucking snakes on a motherfucking graph

Via the inimitable Francis Heaney: Snakes on a Logic Puzzle!

Pacific Air Flight 121 is in trouble! Some motherfucker has released snakes on the motherfucking plane! Needless to say, the passengers are terrified, but there's good news! Samuel L. Jackson, that badass motherfucker, is on the flight! Six of the passengers--Barbara, Cindy, George, Mike, Ralph, and Tina--had particularly harrowing encounters with venomous snakes (a black mamba, a boomslang, an taipan, a gaboon viper, a king cobra, and a rattlesnake), but Samuel saved them all from certain death (he strangled one snake with his bare hands). Can you figure out what type of snake each person encountered and how Samuel took it out?

When you're finished with that one, you can consider the logic behind animal action films from another perspective:

Five separate movies were made soon after Snakes on a Plane appeared in theaters, each with a different actor, animal (one featured lemurs), and mode of transportation (in one instance, animals terrorized a small town on a Segway). All 5 movies signed a different major Hollywood actor...

I haven't done either of these yet (gimme a break, I'm at work), but they're at least high in entertainment value.
