Trying to boost my ego is like trying to inject growth hormones into Jupiter. Sure you can do it, but it can't possibly get any larger than it already is.
Really? Jupiter could easily grow much larger... though I would start by injecting Saturn, not growth hormones ;P ... but it would still be much smaller than the whole Universe... in fact Jupiter is tiny when compared to the Universe... and human stupidity...
And by the way, my hobby is to create worlds... so I guess my ego* could easily be compared to a number of universes... so how does your ego feel about that?
I would say that an ego can not get any larger only if infinity (
) would feel awkward in it's company, though I'm not sure if it is the limit
*well, not really... I'm regularly limiting my ego by committing seppuku whenever I feel it's too big - it feels similar to popping a balloon
