Remembered another as I was reading through these (I love reading the crucible ones and the crazy mishaps that the sparrows cause in pve). I was in The Crucible on Control on the moon riding around a pile causing mayhem. I had killed this one titan three times already while on my spree and I spotted him once again. He was next to a rock wall and saw me speeding towards him. He pops his bubble and just stands there. I drift around for a second then realize the bubble only stops weapon projectiles. What if...I'm the projectile? So I turbo boosted into him and smashed him into the rock wall. :)
