I just found out that the man who discovered Uranus wanted to call it 'George' after King George. Who's anus was more important the King's? And why did scientist at the time think it was so great?

Seriously, Herschel was going to name the planet 'George' but got lobbied into calling it Uranus by the Comedic Guild of Cheeky Scientists. Whose anus is it that we've been giggling at all these years? Is it Hershel's anus?
