Muhammad Ali
Ali's memorial is scheduled to go down Friday morning at Louisville's Yum! Center -- but the crowds started lining up Tuesday night and waited until sunrise to make sure they got a seat. 15,000 tix were gone in about an hour!
Even though they were super early birds, some of the fans got out of hand just before sunrise -- pushing and shoving. Security was able to shut it down before anyone was hurt -- and police are now helping with crowd control too.
