Not only should this woman be neutered, she should be banned from ever having sex again.
Why?

Please observe how her monkey climbs the poles using his stinky feet onto the rings, showing such physical finess... worthy of joining Cirque de Soleil.
God, would someone make him run away to the circus NOW?!

And if one monkey isn't enough, how about two? This one enjoyed swinging himself around and around the pole, occassionally kicking other passengers in the shins without apology.

And of course with two monkeys, you get twice the fun! Watch them compete with each other who can climb to the top first!
Wondering what Mama Peabrain Monkey is doing all this time? Oh, just ABSOLUTELY NOTHING.
Despite the seats available, she isn't half-arsed to tell her evil spawn to sit-the-hell-down. Neither does she apologise to the other passengers when her monkeys kick them in their play.
No. She just watches them with all adoration, cuz come on! They're her SONS.
And since they're ONLY kids, they should be allowed to treat the train as their personal playground, right? Who cares if people might put their hands on those poles later?!

My sentiments exactly, lady.

"If this kid kicks me, I'm gonna kick him back."
His mum takes no notice of the comment, but the other passengers visibly shift uncomfortably in their seats.
If I had behaved like this in public as a child, my mother would've grabbed me by the arm and given me a hard smack before planting me onto her lap or into the nearest seat.
Damn itchy backsides.
