2. The McGuire Twins 770lbs (each)
https://www.youtube.com/watch?v=-ZAl3GqQmNU Okay, so these guys technically count as two separate entries, but given their affiliation I thought Id consolidate them into one. Billy and Benny McGuire (real name McCrary) were, like many big men, billed at a variety of different weights. In their famed photo of the pair squashing an unfortunate opponent, theyre listed at a combined 1,300lbs. Other sources, list them at 784 and 814lbs respectively. However given the fact that theyre legitimate twins, we do have an official figure for their actual weights. The Guinness Book of Records recognises the McGuires as heaviest twins of all time. Billy weighs in at 742lbs and Benny slightly less at 723lbs. The listing goes on to detail that they were often billed at weights of up to 770lbs. Given that this is the most accredited source to hand, well take this 770lbs as their official billed weights, with their actual figures a little less.
