"In some of its more lunatic aspects, political correctness is merely ridiculous. But in the thinking behind it, there is something more sinister which is shown by the fact that already there are certain areas and topics where freedom of speech, in the sense of the right to open and frank discussion, is being gradually but significantly eroded." -- Judge Neil Denison

I shut people's mouths forever
when they do something that
is obscene or when they
talk overly too much.
What am I?

Dammit! Use Tau for my diminutive, will you?
Okay, next one:
The following solitaire game is played on an m by n rectangular board:
First, a rook is placed on some square. At each move, the rook can be moved any number of squares horizontally or vertically, with the extra condition that each move has to be made in the 90 degree clockwise direction compared to the previous one (e.g. after a move to the left, the next one has to be done upwards, the next one to the right etc). For which values of m and n is it possible that the rook visits every square of the board exactly once and returns to the first square? (The rook is considered to visit only those squares it stops on, and not the ones it steps over.)

Outside of 1x1, neither m nor n can be odd. Every time a row is entered from a column, exactly two squares of the row are marked off, and the same applies to columns.
2x2 is trivial.
2xn, where n is even and greater than 2:
Move to second column of first row, then up one. continue in pattern left one, down one, left one, up one until you reach the end of the row, than move to the first column and down one.
If 2xn is solvable, than you can solve mxn (m even) by moving from the first column to the second column, moving up to the third row, filling in the third and fourth rows using the pattern of the 2xn, with the roles of first and second column reversed. This will end in the second column of the fourth row. Move up to fifth row, repeat as needed. Finally, move down to the second column of the second row after you run our of higher rows, and complete the 2xn pattern.
I think we've already seen teh problem where you have a 3 and 5 gallon jog, but need exactly 4 gallons of water.
Let's say you have jugs of size x and y gallons, with no internal markings. You can get any number of gallons between 1 and x+y using these two jugs, by filling and pouring out water as needed.

The answer is: m and n are both 1 or both even.
The answer is correct, but the method is not. You have to turn clockwise each time. You change between clockwise and counter-clockwise.
Oh yeah, and bonus question: does anyone know where I got this?

What is the key property of x and y?
x and y are coprime (they have no common factors). If x and y had a common factor, then you could only get multiples of that factor by filling and pouring.
