That seems to be really grandiose. I've had the whole inflated-ego thing but not quite that bad. I've felt god-like before but I kinda keep it to myself when that happens. At least I try to. My friends called me "Theego" for a while.

Anyway, yes that is something not uncommon in hypomania/mania. Have you ever seen him depressed, hating the world, or really lethargic? It's possible to have several hypomanic/manic episodes though before getting depressed, so who knows. I know that's how it was for me.
