Not really badassity because I didn't do anything, but last night I was going through old files and found a 5 year old 401K statement from my first job that offered any benefits. I hat totally forgotten it existed. I think I only ever put in about $1,000 and left the company before I was vested, but when I checked on it last night it was at $10,000! I've been feeling a bummed lately because I just started saving for retirement and my $2500 401K at my new job seemed so pitiful. Imagine my suprise when my net worth qradupled overnight!
And a good reminder that your money grows even when you ignore it (usually!).
