It's October 2

Which means it is the perfect day to display the most awesome Texas flag of all:

Short version of the Battle of Gonzales:
Texas settlers in the present-day San Antonio area are given a spiked cannon to protect them from the Indians. Four-ish years later, the Mexican military authorities recall this "loaned" cannon and request that it be sent back with the touring military presence. As you can see, this goes over real well.
