You can check out the rest but I thought 2 were particularly interesting. It turns out that Coca Cola makes a kosher brand (extra kosher for the stricter passover diet) which uses sugar instead of high fructose corn syrup.
On a more profound note, it turns out Abraham Lincoln was assasinated during passover. This affected the celebrations taking place at Jewish synagogue.
According to the American Jewish Historical Society, many Jews were in synagogue for the holiday when the news of Lincoln's assassination broke. Altars in temples "were quickly draped in black and, instead of Passover melodies, the congregations chanted Yom Kippur hymns. Rabbis set aside their sermons and wept openly at their pulpits, as did their congregants." Sadly, a time that was supposed to be full of celebration became one of mourning.
