I just learned about Bub's lil dude and her best lady friend (I assume she's adorable too!) from Bub's e-mail today announcing the new arrival:

"As you may or may not know, my dude and my best lady friend procreated to make a lil dude, which makes me a big sis. Rosco Bear Bridavsky was born on April 21st (the Cusp of Power) at 1:27 am, and we have a lot in common. We scream for food, we sleep, pee and poop a lot, are unbelievably good looking, and full to the brim with science and magic."
