A friend of mine had created some animal cartoon images for a software product. He gave them some names that are also idioms...
Spank the Monkey, Whack the Weasle, Club the Baby Seal, Slam the Salmon and Choke the Chicken.
I told him, he should get out more :roll:
I would explain, but that would let the cat out of the bag.
Another good one is "White Elephant".
A valuable possession which its owner cannot dispose of and whose cost (particularly cost of upkeep) exceeds its usefulness.
Sick as a Parrot - See Monty Python Parrot Sketch. REALLY sick - (Dead)
