A mad scientist decided to go to the brain transplant clinic to refresh his supply of brains. The secretary informed him that they had three kinds of brains available at that time.
Conservative brains were going for $20 per ounce and Independent brains were getting $30 per ounce. And then there were Liberal brains which were currently fetching $1000 per ounce.
“1000 dollars an ounce!” he cried. “Why are they so expensive?”
“Well” she explained, “It takes more Liberals to get an ounce of brains.”
