My brain being the insanity that it is, first associated 'jerks' in the sentence as the derisive kind of word used for males who are insensitive, foolish, cruel, unrefined, obtuse etc as soon as I read it. As if the train departed with some guy passengers who were such jerks! Then as I read the sentence towards its end, the meaning and context became quite clear.
But still the thought lingered, and grew strong and clear.
Ladies and Gentlemen!
Boys and Girls!
Deviyon aur Sajjanon!
Jerks and Screeches!
Welcome aboard the Toyland Train!
A 'Screech' seems such an apt term for a female who is acting all hysterical shrieking bitchy screaming drama queen for a reason that is actually no reason at all!
A Jerk X A Screech!
"You are such a jerk!"
"You are such a screech!"
Ah what a 'great' experience it would be to travel in a train compartment full of such jerks and screeches!
