It's pretty awesome, especially spelled
Baltazar. Don't know that I'd ever use it on a real person, though. When I used to watch "Alias", my dad, sister, & I would always mock the name when
Balthazar Getty's face showed up on the screen, which probably had more to do with the fact that we didn't like his character. But still...it's an easily mockable name. And a
Baltazar would be lucky to end up with the nickname Balt and not Balls, or something to that effect.
