I have loved both the Roadside Picnic and the Monday starts on a Saturday. I've specifically tracked this edition for the Tale of Troika to see what else the wizards/scientists at NITWIT were up to next and I loved it.
This has to be one of the most scolding satires of the Soviet bureaucracy, especially their tendency to make a committee for everything. I have recognized so many people from both my experience, and from stories from other people I know in these characters that it has taken me four or five times as long to read through this short story simply because I just couldn't stop laughing at times and had to take breaks.
The ceremonial launch of the elevator and the request for a purple Extraterrestrial with four eyes and four arms to prove that he is in fact not from Earth really got me... you have no idea.

I do not wish to reveal more for I will only spoil the jokes. If you liked Monday starts on a Saturday, there is a good chance you will love this story even more.
