"I'm going to take a moment to set the record straight, I see there's a lot controversy over this 'Whoopty' thing.  So first and foremost, CJ made a hot song .  But the content that he used is not his content.  So his foundation is based off a lie.  He's not Whoopty.  He don't know nothing about Whoopty.  He just saw a fly splash and jacked it.  Which is a smart move but in life you gotta show respect and you can't live a lie.  Now you jacking something that they got dudes in jail for ... they gave me 30 years for a lifestyle that you talking about but you never lived," Johnson explained.

There's also a video that claims to show CJ being beaten for faking his affiliation, although it is not confirmed as authentic.
