butter

Did you know butter is a different shape from coast to coast. So that made me wonder... where is the line where the butter changes shape? Is there yet another size in the middle? Does it go by time zones? So there would be Eastern butter, mountain butter, central butter, and pacific butter? Hey Denver what is your butter like? So I am just wondering is why the long skinny butter on the east coast and the short stumpy butter on the west? Just a thought.
