he would dwarf Ronnie in person.
Most fat men at that height would. Dude's arms are huge, but they are not pure muscle like Priest, Ronnie, or Marko (whatever his name is). If dude dieted down, they might be a legit 22.
Its kinda like how Grizzly Brown (now dead) had the "world's largest muscular arms" according to Guiness, but those things were bulk, mostly fat, and they were like 23 inches "cold"
