What would I do? Stand there and start screaming at Hulk to leave me alone, I'd probably start crying, etc.
I'd be like
"PLEASE HULK! DONT KILL ME! IM SORRY FOR WHATEVER I DID!" and I'd fall on the ground, roll around, etc. This would probably stop Hulk for a second while he watched me.
Remember, The Hulk isnt completely un-responsive, hes just alot less intelligent, he probably wouldnt kill a dude crying on the ground, or he wouldnt know what to do.
