EXCLUSIVE CLIP: Big Black's Mesmerizing 'Hot Dog'

Christopher "Big Black" Boykin came up short when trying to take advantage of the new skinny jean craze on the next "Rob Dyrdek's Fantasy Factory."

"Dude, this is hot in the streets right now," said Big Black while modeling a pair of his skinny jeans made for plus-sized men under his BB clothing line.

"This has nothing to do with size, but from right here it looks the same way the backside of a large cow looks," Rob joked, clearly skeptical about Big Black's fashion choice.

Click the video to hear Rob's improvised song about Big Black's "bulge," which the skateboarder "can't keep [his] eyes off [of]." You can see the entire episode tonight on MTV.
