Snakes on a Train?

Boston Herald - BOSTON - It is a hefty cleaning bill for a Massachusetts woman whose 3-foot long boa constrictor slithered away from her on a Red Line subway car in Boston and hid in the car for nearly a month.
Transit officials want 30-year-old Melissa Moorhouse of Allston to pay $650 to cover the costs of disinfecting and sanitizing the train to protect passengers from germs such as salmonella that may have been left by the Penelope the snake.
Penelope’s owner had traveled around with the Boa around her neck and lost it between the Broadway and Andrew stations on Jan. 6. It was spotted on the train earlier this month by a commuter.

I'm sick and tired of these mother fucking snakes... on this mother fucking train?

Thanks to Nick for the tip.
