Just finished watching the 1960 series Batman on MeTV. The episode's villian was Egghead played by Vincent Price. One scene had Egghead stealing from the Gotham City Treasurey which had a sign that said "City Tax Funds Are Kept Here".

In one fight Egghead throws out an egg bomb that contains laughing gas and the last fight of the episode had Batman and Robin fighting Egghead and his gang at the "Old MacDonald Egg Farm" with each side throwing eggs at each other much to the dismay of Old MacDonald.
