Worf Feels Immense Pain

This is the story of how Lieutanant Commander Worf of Deep Space Nine was made one day to feel immense pain.
 
He was having dinner with his beloved wife, Jadzia Dax, who passed at too young an age.
 
The dinner was a large and hearty one, and Jadzia ate well, devouring near everything in sight. Then came the desserts.
 
Jadzia hungrily eyed the confection-filled cart, and for a moment her need for chocolate easily outclassed Worf's previous lady.
 
Worf expressed a concern. This is how he became badly injured.
 
"My Wife--Is it not perhaps a good day--To Diet?"
