Ok, I admit it. I asked the typical female question: WHY!!?!?
But then I looked up the answer. Thought you guys might find this interesting:
Anvil launching was once used as a substitute for fireworks during celebrations. One such noteworthy celebration was held on the day the state of Texas voted to secede from the Union. On February 23, 1861, Texas Ranger and prominent Union supporter, Thomas Lopton Campbell Jr., was held captive and forced to "fire the anvils" in the streets of Austin.
Although its practice has lessened in recent years, enthusiasts still participate in anvil launching events.
Whatever it's origin... FREAKING AWESOME!!!
