SadPath

Given an if-then-else (LookBeforeYouLeap)...

  if happiness
    foo()
  else
    sadness()
  end

...the if statement's condition and then block should prefer the HappyPath. The SadPath should only appear in the else block.

Or perhaps CoupleLeapingWithLooking:

 try {
    foo();
 } catch(Exception e) {
    sadness();
 }
