Excellent suggestion. Feed them politician brains and starve them to stay-dead.
It'd be alright to feed them politicians brains if they weren't so darned expensive....
You see,, this zombie goes to his local butcher to pick up some brains and was comparing prices. Like cops brains were $4.95 per pound, engineers brains were $5.95 per pound, and a hookers brain was $7.95 per pound. Then he notices politician brains as $295.95 a pound: "Hey, what's up with the price on politician brains, why are they so damned expensive??"
The butcher ambles over and says: "Well it's like this, hookers brains aren't as tasty or as easy to come by as engineer brains, for example... and cop brains are so cheap because they haven't been used nearly as much.
Yeah, OK, but that still doesn't explain why politician brains are $295.95 a pound."
"Well that's easy," replies the butcher: "it takes about 300 of the suckers to make up a pound."
