oh, barrowman
I've never actually seen John Barrowman act, but I still enjoy his antics. Case in point, taken off Magiksara's Tumblr (from the DVD commentary of Eccleston's run on Doctor Who):
When Jack kisses Rose and the Doctor goodbye, John Barrowman made a special effort to kiss both actors in exactly the same way... except on one take, when he kissed Billie Piper as usual, then said his line to Christopher Eccleston, started the kiss, and didn't stop until they fell on the floor.
