A: Toblerone

Triangular and deadly like the fin of Spielberg's shark
But made of lovely chocolate either milky white or dark,
Lurking in its cardboard tube, so peaceably it waits
For it's temptingness is deadly and you cant avoid your fate -
Like a cross between Medusa and those Sirens of the sea
Once you've glimpsed its invitation there's no chance that you can
flee
And you grasp it, clutch it, stroke the box and hold it very
tight
Anticipation breathless at the imminent delight
Though you know it could be fatal you've got faith and iron-will
You can make it last a lifetime, every day a brand new thrill
But you taste it, chew it, feel its scent, its texture on your
teeth
And willpower goes by the board - temptation sends a wreath.
One triangle, then two then three, the fourth is close behind
Your mouth is being shredded but intoxicated mind
Pays no heed to painful chewing or fatigue within the jaw -
Commands the hands to fetch the tube and break off seven more.
Oh Toblerone you deadly, you relentless, you addictive little
swine
Even as I curse your goodness, oh thank God that you are mine!
