Yes, I am

Further evidence of my invincible-ness of yesterday:

I walked in the middle of the street, wearing nothing but socks.
Needless to say, no cars touched me.

Then I bought a scratch and win.
Indubitably, I won.

I then proceeded to press. I used my winnings ($2) to buy 647. I invested in the following numbers:

• 6 (of course),
  
• 18 (my birthday),
  
• and a bunch of prime numbers, because prime numbers are invincible
  Like attracts like, remember.

And today, it rained. My invincibility shone through once again, because I didn't wash my car yesterday.
