We have been naming them all lately. It's fun and it gives you some frame of reference to remember which was which. It gives them more personality too. Some of our recent names:
Wit Man's Burden - a Wit that took over 4 hours to sparge
Bitter Defeat - brewed the day after the Presidential election...an English Bitter
Vote For Pedro - a great Pale Ale
Flaky Salmon - A pale made with all Chinook
Barn Floor Bitter - my brother spilled a bunch of grain all over the floor...some made it into the mash anyway

GLGA - a house standard...stands for Gregg's Little Girly Ale (Gregg is me). A buddy of mine named this because he was convinced it would be lawnmower beer. Just a straight ahead Pale Ale with no crystal/caramel malt.
Sir Greggory's Ale for Young British Ladies - Sounds sketchy, huh? It's a GLGA made with British yeast and hops.
Black Tuxedo - A really silky smooth stout we have on tap now.
It goes on and on...I find naming them is fun
