me and friend #1, 2, and 3, were atop a desert hill in which there's a grass patch. we chillin, a little mad halfway through our session 'cause we didn't preroll, but we had bowls, so it was good. i was laying back and friend 2 and 3 are still trying to roll up. they call me, i sit up, and all of a sudden i hear this rattling noise begin. first thought in my head is "shit.. a rattler!" i jump off, and run down the hill, and i hear friend number 1 follow. we're running through desert bushes and such, and i hear him fall. he gets back up we keep running to the bottom of the hill. i point out he's bleeding, which he didn't notice. we got him cleaned up and returned to look for our other friends. friend 2 is fazed, has no idea what's going on.. and then friend 3 looks at us and says: "dude, it was a sprinkler" good times.. and now friend 1 has scars that he'll carry for the rest of his life.
