If you don't get it right, there will be TRouBLe

Actually the clock thing works perfectly. It is the most intuitive way to remember it, at least for me.

Tricky Rectangle Border Logic ?

Why don't just remember that the order goes clockwise starting from the TOP:

TOP -> RIGHT -> BOTTOM -> LEFT

Another attempt:

Tyrannosaurus Rex : Big Lizard

Just think clockwise, it's the easiest way. Starts at the top and goes around... much easier to remember than some silly phrase (provided you know how to read a clock...)

TRouBLe is best for me. And if only 3 values are shown, it's Top, Sides, Bottom - which for UK users spells TSB (the bank the government had to bail out using our money) - so TRouBLe and TSB are closely linked!

TROUBLE is always a secondary reminder for me, since I first think of the clockwise direction but might need to remember where you start; however, the 3-value shorthand was always confusing me until I realized the middle, (or second) value needs to represent two values (the sides). So, three values - the 2nd being 2 values - helps me remember that.

The clock trick works for the 4 number shortcut, but is there any logic to the 3 and 2 number shortcuts? 1 number and it applies to everything, and that makes sense, but

1 = (T/R/b/l) 
2 = (T=b) (R=l)   
3 = (T) (R=l) (b)  
4 = (T) (R) (b) (l)

It just doesn't seem logical at all. But... First value pertains to Top, Second pertains to the Right, Third is the bottom and Fourth is the left; A number is not specified if it's the same as its opposite. Horizontal and vertical MUST be declared unless all values are identical.

In other words, you always specify the Top and Right values, bottom and left fall in as required.

Think that you're reading Arabii or Hebrew: read from the top of the page, right to left to the bottom. ;P The good thing about this "rule" is that it works for the 3 value version too: top right-and-left bottom

Actually, i allso thought it was hard to remember, but as soon as I discovered it was the direction of the clock it was easier.

It is

left

not what you have

Remember driving lesson:

Turn Right Before Left

If you're old enough to remember the original Star Trek TV series (you know, with Capt Kirk), well first of all, you're too damn old. But there is "The Trouble with Tribbles" episode. Both nouns in the title work. I've used that in the past, but also prefer the clock analogy.

Whenever you strike with a given situation, just think of a clock-wise rotation i.e., way the clock rotates from 0 to 60 in a circular rotation.

Clock thing is easier to remember than the word TRouBLe (as marked answer) in my opinion since the word trouble belongs to English language and all those minds native to English language might find it easier to remember the word TRouBLe in relevancy to the given situation but not others who only use English language when they really have to.

Same is not true with clock-wise rotation of a clock, when it comes to remembering something (as asked it the question) since clock-wise-rotation is a very well-known phenomena world-wise.
