Clones had their own particular sense of humor. It probably had as much to do with their childhoods or lack thereof. Being grown in a vat with your head full of facts and trade skills but without any real experience was a different way of coming into this world.
Clone 1234567 took a lot of shit about her name. Not from humans. Humans didn’t usually take the time to even notice. But other clones found it hilarious.

The big black letters made it even more noticeable.
