How many seconds would Bruce Lee need to kill Ali or any boxer in a street fight?

@The Insignificant One, who really cares if Bruce Lee could kill Ali or Tyson in a fight? Bruce Lee is dead (may he be RIP), so why do we waste our time asking insignificant questions like this? and why do we waste our time answering dumb questions like this? don't we have better things to do then ask, if this guy could kill that guy blah blah blah.
