I once found an abandoned cat once and named her Useless. A few months later I found a lost kitten and named her Ditto. I had to give up those two cats and later found an abandoned cat that I named Dono. I named him that because I "dono" what to name him.
I also found an abandoned puppy on the St Louis freeway and named her Freeway.
I read of a lady who named her cat Whoopee. She decided to change it after she found herself on her front porch late one night in her nightgown yelling, "WHOOPEE, WHOOPEE".
