Under Attack...in our backyard?

Last night, as Ev and I were reading before bed (we are going through the Little House on the Prairie series) we heard a loud ping on the window.  A few minutes later another one, Jamie had heard it from the living room and came in trying to figure out what was going on.  It sounded like someone was shooting the house with a bb gun, but from our backyard, which didn't seem possible.  So we continued reading and Jamie grabbed a flashlight, as it was just getting dark and went outside to try to figure out what was going on.

After a few minutes of investigation he solved the mystery....it was the wisteria.  Neither of us had any idea how wisteria propagated, honestly I'd never thought that hard about it.  But our back deck is surrounded by it and it had just started blooming.  I don't know what triggered it but the pods that had been hanging off the plant since we moved in went off and started exploding right and left and shooting their seeds all over the yard, house, and deck.  So obviously story time was over (exploding plants are pretty cool) and we all went to the deck and watched/got hit by/picked up the seeds going everywhere.
