Talk:An Under-Edd's-Hat Theory/@comment-4241330-20130503153155/@comment-98.114.141.54-20130504034455

The hat is just a hat, not a black hole- if he had a freakishly huge head, wouldn't it affect the shape/size of his hat? Also, brain size isn't as important in determining intelligence as the number of connections/density. Crows are notorious for being highly intelligent, comparable to apes- yet in relation to their bodies, their brains are tiny.
