Machete-Wielding Charlie Sheen -- 'I'm Free At Last'

Charlie Sheen just climbed to the top of a building in Beverly Hills, pulled out a MASSIVE machete' ... and waved it around in post-termination triumph ... all while drinking a bottle of Tiger Blood.




It all went down at the Live Nation office building in Beverly Hills ... where Charlie said he had a top-secret meeting with some old friends.

After sheathing his blade, Charlie was asked how he felt about being fired from "Two and a Half Men" -- to which he replied, "Free at last ... free at last."
