Dec 10, 2013 at 16:22	comment	added	David E Speyer		Thanks! I don't know about $K_{6,6}$, but $K_{7,7}$ is easy: Take the Fano plane and the dual Fano plane. For a point $p$ and a line $\ell$, put $p \to \ell$ if $p$ is on $\ell$ and $\ell \to p$ otherwise. Any two points are on a common line, and any two lines both miss some common point. I'm waiting a little bit on the bounty to see if anything more awesome turns up.
