While Twitter limits B.o.B’s thoughts to 280 characters or less, Instagram offers more freedom to discuss another one of his theories, this one regarding the existence of slavery. In a since-deleted post, he pondered, “They say slavery lasted 400 yrs… America is only 250 yrs old… You ever seen a slave ship? They can find a billion year old dinosaur bone but can’t find any slave ships. #AseerTheDukeofTiers #apparently #SlaveryIsNotInMyDNA #WeBeenHere.”

Similar to his quest to determine whether or not the Earth has a curve, B.o.B. questions the legitimacy of slavery by pointing to an apparent lack of slave ships. He also uses dinosaur bones to further support his stance. Wonder if he’ll be launching another GoFundMe anytime soon.
