"Two Plus Two," by Alex Eaton-Salners

Constructor's Comments

Some of the other theme entries that got left on the cutting room floor:  GOTHAM CITY, AS GOD IS MY WITNESS, and GOLDSMITH.  There were also many possibilities with GOOD as the GO (IN GOOD SPIRITS, GOOD SAMARITAN, GOOD PUBLICITY, etc.).  Unfortunately, there was only room for one due to duplication concerns.  I was really lucky to get GOT A BITE and GO WITH IT to symmetrically interlock with ALGORITHM and GOOGLE HIT.  The latter pairing is also aesthetically pleasing, since complex algorithms underlie Google's search function.
