Marry, Shag, Throw of a cliff...
geminiscorp gave me Jason Isaacs, Ronald Weasley and Andy Ryan (from Kathy Reich's Bones books, not the series)
I thinkI'd have to marry Jason. Endless sex, and I'm sure I could persuade him to dress as Lucius for special occasions.
Ron Weasley - Throw off a cliff. He never even gets better with age - as the crapilogue shows. Kill him, Kill him!
Andrew Ryan - I couldn't find a picture of how I imagine him, but Mark Harmon comes close. Shag, several times, but just too much baggage to marry, I'm afraid.
