Okay, it's pretty simple. All you have to do is say "I saved the person above me by BLAH BLAH" and than you also say "I accidently fell off a cliff!" I'll start.
I save Bob by placing a trampoline under where he was about to fall.
Oh no, while I do that, a rocket is about to hit me, when!
I, Harry Potter, use my magic wand and cast a spell towards your magic and they collide and cause an explosion, but I was too close to the explosion and its flames chase me in a narrow corridor.
