In WW Hulk #2, Richards states that Amadeus Cho is the 7th smartest person in the world. Well, obviously Richards thinks he is the smarter. Who else? Banner, Doom, Strange? I've not read in a year and a half, so I depend on you, Pedobears, to see me through this trial of trivialness. You can't really rank them since it's not written anywhere and it's fairly subjective, but it's fun to mess around with.
