Father's Day is coming up. And while most fathers are great role models, there are some you should be glad to have never had to call Dad. Here's a list of just some of the few worst fathers in history:
Byron Keith Perkins -- Temporarily let out of prison in January 2006 to donate a kidney to his ailing son, Perkins instead took off for Mexico with his girlfriend. He wasn't arrested until more than a year later in Puerto Vallarta.
Constantine the Great -- For reasons that remain unclear, this Roman emperor ordered the execution of his son, Crispus, in 326 A.D. and erased his name from official records. Monuments to Crispus were also destroyed.
Bruce McMahan -- This Florida multimillionaire loved his daughter so much, he married her. Yes, that's right. The pair secretly exchanged vows in 2004 even though McMahan was still married to his fifth wife and his daughter, Linda Schutt, lived with her husband in Mississippi. They, too, are now divorced.
Johnny Eric Marlowe -- Already convicted of child neglect and assaulting his wife, this North Carolina man was charged with child abuse for circumsizing two of his infant sons with a household utility knife in 2005 and 2006.
Ivan the Terrible -- In 1581, this Russian tsar beat his pregnant daughter-in-law as punishment for wearing revealing clothing, causing her to miscarry. His son, also named Ivan, agrily confronted him and was struck on the head with Ivan the Terrible's scepter. The younger Ivan died a few days later.
Josef Fritzl -- He's currently serving life prison sentence for keeping his daughter Elisabeth in a cellar beneath the family home in Austria for 24 years. He repeatedly raped her and forced to bear seven of his children, three of whom she raised in the dungeon while three were taken upstairs to live "normal" lives. Elisabeth's plight was only uncovered in 2008 after she slipped a note in her daughter's pocket when the girl went for treatment at a local hospital.
Herod the Great -- An ambitious but cruel and paranoid king of Judea, he infamously ordered the executions of several family members, including his second wife and three of his sons.
Marvin Gaye Sr. -- A day before his 45th birthday in 1984, soul music legend Marvin Gaye was shot dead by his father, Martin Gaye Sr., after intervening in an argument between his parents. Marvin Gaye Sr. said he shot his son because he feared for his life after his son struck him during the argument. He ultimately pleaded no contest to a voluntary manslaughter charge and received a six-year suspended sentence and five years probation.
Michael Jackson -- Accused several times in his career of molesting children, Jackson's parenting skills were most famously questioned when he dangled his infant son Blanket over a balcony before screaming fans in Germany in 2002. Some called for his arrest on child endangerment charges.
Peter the Great -- Not known for his warm parenting style, this Russian tsar famously contributed to the death of his first-born son, Alexei, who had been convicted of conspiring to kill his father despite a lack of evidence. Before his planned execution, Alexei died from wounds sustained during a torture session in his prison cell.
Ryan O'Neal -- He's most remembered for firing a gentlemanly "warning shot" during an argument with his son, Griffin, in 2007. But O'Neal is also said to have put daughter Tatum on a cocaine diet to help her lose weight and told her "You cut the wrong way" after her failed suicide attempt.
Shawn Kemp -- Best known for his NBA stint in Seattle, The Reign Man also bore seven children with six different women, and there are rumored to be many more. He's also been the subject of several paternity-related lawsuits.
Thomas Boleyn -- He is said to have pressured his daughter, Anne, to marry King Henry VIII, even though the king was already married at the time. Three years after the controversial marriage, Anne fell out of favor with the king and was beheaded on charges of high treason. Her brother, George, suffered the same fate. Thomas, meanwhile, is said to have done nothing to protect them.
Woody Allen -- In 1992, he admitted to being romantically involved with Soon-Yi Previn, the adopted daughter of Mia Farrow, Allen's longtime companion. Farrow discovered the affair when she found nude pictures of her daughter in Allen's apartment.
