A flat mate.
None. They just sit in the dark and blame the Jews.
Only one. But they have to sit in the dark room for a year, first, to make sure that the lightbulb is out.
No Biggie.
They are always willing to stick their neck out for you.
To learn about gorilla warfare.
So you can tell him apart from a gooseberry.
Because he wanted to see his flat mate.
