UFC announcer Bruce Buffer and his famous bro don't joke about protecting the 5 most famous words in pro fighting -- but says "Saturday Night Live" is getting a funny pass ... a very pricey one.
The 'Veteran Voice of the Octagon' was outside Gold's Gym in Venice, and told us why "SNL's" Mayweather/Pacquiao skit -- which included Michael Buffer's "Let's get ready to rumble" -- isn't costing NBC a cent.
Normally, Bruce and Michael charge handsomely -- at least 5 figures -- for an individual or production to use the famous catchphrase.
Bottom line in this case -- Bruce gives Taran Killam's version a thumbs up, but it's far from open season on "rumble." If you want MB at your next birthday party ... get ready to payyyyyy!
