Creepy but cute actors from Showtime

For a while, I had a crush on Martin Donovan as Peter in Weeds. As soon as I started watching Dexter, Michael C. Hall became the new object of my "Creepy but cute actors from Showtime" affection. I'm watched a big chunk of the 3rd season tonight (it's like crack, it really is). Knowing that in real life Dexter is married to Deb kind of ruins it all for me. The crush and the show.
