Absolutely agree with you Tom!!! NO to the name Sheldon for a tortoise. Or Shelly either.Everyone doesn't. I have no tortoises named Sheldon and never have.
Love it!My male desert tortoise is a rescue that had been run over by a car. The person who found him took him to a vet who repaired the broken shell with auto body filler, bondo. After the tortoise was given to me, his new name is Bondo, James Bondo. And you have to say the whole thing, not just bondo.
My DT is named Chug, for his dogged determination. No obstacle is too big, too high, or too heavy! He reminds me of a long train trying to get up a steep hill. Chug, chug, chug...
Of course he also has nicknames; Chugster, Chug-a-Lug, WHAT are you doing?, no..No..NO!!, and Don't eat that!
