"The Dudesons" star Jukka Hilden is at it again ... with another insane stunt that ends with a SCORPION TRAPPED IN HIS MOUTH!!
Jukka -- a member of the four-man stunt group from Finland -- was the lucky loser who had to stuff a live scorpion in his mouth, and attempt to duct tape the sucker in there for a full minute.
Why? Because playing with alligators is so last week.
There's gotta be a better way to make a living.
