'Dexter' baby pictures aww how, uh, cute?

 "Dexter" has a baby on board this season.

As we all know, our favorite blood spatter expert is experiencing the joys of fatherhood this season.

These photos were part of the darkly humorous poster campaigns at July's Comic-Con in San Diego playing up Dexter Morgan's offspring joining the show this season.

And if you would like your little bundle of joy sporting these serial killer puns, check out the Showtime site for your "Dexter" onesies and bibs. We kid you not. Heh.
