UFC legend BJ Penn was involved in another bar fight in Hawaii -- this time, the 40-year-old was sprawled out on top of another man raining down punches and TMZ Sports has the video.
Penn was at the Lava Shack on the Big Island on Tuesday when he got into it with another dude -- and in classic Penn fashion, the fight ended up on the ground. We have a pic of Penn at the bar earlier in the night. You can see the clothing is the same.
Penn had his opponent mounted -- and his legs were hooked in -- and he threw at least 4 ferocious shots to the other man's head .
