According to Facebook, I'm a 103 year old astrophysicist who speaks 21 languages. I got my first job in 1929 at Sam's Blacksmith Shoppe, was hired by NASA in 1959, and Co-Founded PurposeMatch.com in 2011. I speak English, Ingles, Spanish, Mandarin Chinese, Russian, Arabic, Hebrew, Hindi, Japanese, Afrikaans, German, Italian, Norwegian, Swedish, Portugese, French, Greek, Swahili, Hawaiian, Elvish, and Klingon.
Which means that the ads I see (thanks to retargeting) are pretty awesome. For example...
Caskets and Funeral arrangements
I know I'm 103 years old, but seriously - has anyone ever bought their own casket from a Facebook ad?
"Swedes in California" t-shirts
Talk about zeroing in on your target market. Nailed it.
Job postings for Astrophysicists
I do listen to a lot of Neil DeGrasse Tyson's podcasts.
Ads in many different languages
No idea what they say, but I bet they're awesome. My favorite are the Norwegian ones. Still waiting to see one written in Elvish or Klingon.
