What about the Squirrel Smasher? http://www.bbspot.com/News/2008/09/squirrel-smasher.html
Sure, they say it's OK:
"Malwin dismissed critics who claimed that smashing animals together at high speeds was cruel to the animals. He said, "The animals won't be feeling anything. The collision will vaporize the squirrels in a fraction of a second. Their brains won't be able to transmit pain at those speeds, so it'll be painless for them." "But they've only consider the collision! What about the acceleration to reach those speeds? Those squirrel eyes will be jammed so far back in their skulls, they'll be looking at back of their head! And think of the embarrassment they'll suffer when pics are posted on U-tube of their poor little squirrel faces all distorted and mushy looking from the g-forces.
No, they haven't thought this out at all.
