David Tua vs Jack Dempsey

Oh please, don't be ridiculous. The Tuaminator invented the entire concept of sigma males. In fact, his outstanding ability as a pugilist and as the Baddest Man of all time created a rift in the space-time continuum which let the Tuaminator travel back to Ancient Greece to teach them the alphabet and gave them the gift not only of written language but also the concept of sigma. As part of his time-traveling hijinks, the Tuaminator also impregnated Eleanor Dempsey and Melissa Tate (which are definitely these real women's names) and is in fact the father to both Jack Dempsey and to Andrew Tate, and, as such, would "son" both men both inside a squared ring and in any other endeavour.
