Every statue of the Buddha I have seen depicts him as having long ears.
Did Buddha really have long ears? If so, why and how did he get long ears?
The earlobes are elongated, partly to indicate the Buddha is all-hearing and partly as a reminder of the heavy earrings that weighed them down before Siddhartha renounced material things to seek enlightenment.
Ah ha, the Ears reference comes from the 80 minor marks: ref: http://news.fjnet.com/english/abcOfBudd/200606/t20060626_30901.htm (credit to yuttadhammo for solving the mystery)
The idea that the Buddha or a Buddha has 32 marks or physical qualities popped up in Buddhism and iconographers followed this list, but long ears isn't on that list.
These marks are historically conditioned, related to the ideal of beauty at that time, or at least of the people writing those lists; seemingly rational arguments for long ears are a part of the idealization game, be they accurate or not. D. Ingram in Mastering the Core Teachings of the Buddha (pg. 302):
The old Theravada texts go to great lengths to list the 32 interesting physical qualities of the Buddha, such as having 40 teeth and arms so long that he could touch his knees without bending down. It is interesting how things change, as in our modern context that would make him look more to us like a dentally challenged Cro-Magnon than a spiritual superhero, but I digress.
