This is the best example I've seen so far:

I actually intend to fix the universe (or at least throw some padding atop my local region of it, as disclaimed above)

The padding version seems more reasonable next to the original statement, but neither of these are very realistic goals for a person to accomplish. There is probably not a way to present grandiosity such as this without it coming across as arrogance or worse.
