Women, you've know it all along: 
men are stupid because of you.  Studies have shown that men's IQ drops  significantly when interacting with a pretty woman, which completely explains why that one cashier at the grocery store kept telling you that story about puking, even though it was clear that the  story was going nowhere good.  Men can't be responsible for our idiocy, so women need to stand up and acknowledge the fact that 
their tits are ruining mankind.
