Rangers fan--saw the post from the main page and I love dogs. My own pup has an odd name. I adopted her when I was doing a run of Shakespeare's The Merry Wives of Windsor, and I had to bring her to the show because I didn't have enough time to get her home and settled before curtain. The woman who played my wife in the show decided that my 8 week old, 5 pound German Shepherd puppy was a better prop than the hand-bag that she had, and--without telling anyone--walked out for the opening scene with a tiny sleeping puppy in the crook of her arm instead of her prop. Pup stole the show and we joked that she was the "Merry Woof of Windsor."
Ended up naming her Windsor.
For your situation, you could go with something unique like "Trophy."
"Four" might be another option (to represent the number of cups).
