In a moment of pure debugging hell and hate, I put an alert with the text &quot;WTF!&quot; for a condition that should never occur. I could never get it to reproduce and, due to some distraction, I checked in the code with the alert still there.<p>I probably don&#x27;t have to mention who got that alert while working one day.  The president of the company, of course! Luckily for me it was not a customer-facing function &amp; they found it funny.
