"A Orin Looms." -- I thought this was great cause, hey, guess who I got this from! And as you've proved, loom he does in deed!

"Larson, I Moo." -- this is doubly fitting, firstly in the way you mentioned (as Gary and the cows are inseprable like inseprable things are), but also because in gradeschool I used to moo, literally, all the time. One of my friends still teases me for it!
