Well, you could knock me over with a feather

Brady is Irish?  Well you can rock me to sleep tonight.  I didn't think the name was English or Scottish, so I have no idea what I thought it was.  Los Angelean, perhaps.  Wikipedia says:

Brady is a surname derived from the Irish surname Mac Brádaigh.  In a listing by the U.S. Census Bureau of the Most Common U.S. Surnames Brady is ranked at #411.

The bastard even has a cool coat of arms.

If this were Jeopardy I would have picked Jim Kelly, which gives me an excuse to link to this.
