Broken glass

The Talmud dictates that there should be “awe and trembling” upon a couple getting married. The destruction of a glass has its roots in superstition, but it took one pissed-off rabbi to carry the odd practice over to Jewish weddings.
But instead of smashing a glass as tradition dictates, most Jewish weddings these days have the groom smash a cheap light bulb wrapped in a napkin.
Which means, of course, those weddings aren’t real weddings at all. Those couples are living in sin and shall be damned for it.
What do Jews break for a divorce?
The pre-nup, of course.
