Apparently an English degree from Dartmouth is quite easy to obtain these days. Actually the adjective pusillanimous would be sufficient to modify the noun "cranium". Adding mentally is simply redundant. You are making great use of that desktop thesaurus, but please for the sake of your alma mater use proper grammar.
And speaking of classic internet responses.......yours is digital cowardice at it's finest. Hurling unsupported insults and accusations with no evidence or facts. You can't even seem to address the topic in an intelligent manner, but rather resort to attempts at plebeian humor to camouflage your apparent intellectual shortcomings. Let the flaming continue....it suits you well.
