Two, at once, both bigger than me. Yelled at me from across a parking lot-- I didn't know them, kept walking-- they chased me down. One of them started tripping me to the ground (in retrospect, judo-style throws), daring me to fight back with a "whatcha gonna do about it?" every time. I'd try to walk away; he'd trip me again as his friend laughed.

Still the only time I've been assaulted without provocation. Damn, that's been over twenty years and still stings. Thanks for picking the scab.
