What idiot thought of bringing frankincense and myrrh?  They sent the wrong wise men, who picked the wrong presents. 

What the Arabs did was very clever.  They got the perfume from Araby and India at a knock-down price, adulterated it, and sold it to the Franks (alias, the Christians) at ten times the price. The Franks never knew the difference.   Nowadays we treat this typical bit of oriental  free enterprise as something near to mystical and holy.  Just shows.  If only the Franks had done some research.   Meanwhile myrrh was for embalming people.  It is best to embalm them, and most effective, when they are still just alive.  Once they are cold, their bodies are more likely to  putrefy.  Poor Jesus!  The little mite must have been terrified.
