Twenty-seven and the year 1939 have been pretty prominent throughout my run. Gordon is Captain of the 27th Precinct in Gotham, The Roman's Holiday Massacre took place in 1939, and I'm sure some other examples are in there that I'm forgetting. Let it never be said that I don't lay it on thick.

I've caught most of the references but since this one was pretty spelled out I had to make a comment.

Honestly, of everyone's posts, yours tend to be the most fun to hunt for Easter Eggs.
