I am seriously considering smiting your ass right now Unhelpful Bastard Man 
Unhelpful? Me? My dearest rigger-girl, you wound me deeply! (And I don't just mean with your crotch-ripping drones, eiather

) You asked about when he's at home. As far as I know, Galactus has no home, he just roams around devourering inhabited worlds (except in one universe where he is the "Restorer of Worlds" breathing life into dieng civilizations and planets). So maybe when he does get a chance to go home, you know, once every hundred million years or so, he may well BE homer simpson. You don't know. Galactus is an imortal, invulnerable, galatic-level being.
