Like footage of a UFO or a clip of Bigfoot trekking through the woods, video has emerged of the elusive beast known as Kimbo Slice training in an actual gym for his upcoming Bellator 138 fight against Ken Shamrock.

It seems American Top Team is where Kimbo has been doing his thing, and in the video we see him hitting pads with former WEC champ Mike Brown. That’s a good sign, no? Because it’s totally within the realm of possibility that Kimbo would be preparing for his June 19 fight be smashing homeless men in some boatyard.

Now the big question is where Shamrock is training (or if he even is). I hope it involves the Lions Den and lots of steak and chicken.
