63% of women contain male DNA in their brains. It is posited that it may be sometimes from DNA transferred in utero from an older brother (leftover graffiti in the womb?), possibly a leftover bit from an absorbed twin…but the most likely form of transmission is from unprotected sex.

In other words: you’ll never truly be able to be rid of your ex boyfriends.
Can I blame my vote for John McCain on an ill-vetted one night stand?
“It wasn’t me, it was the conservative DNA I absorbed!”
