I thought they were kind of pointless characters, of course I liked them both but why did they come? I think Pete came that way Andy and Erin could break up,and add a little more spice to the show when Andy was on his boat for 3 months, but Clark was kind of pointless. The only thing he did was bring Erin and Pete closer together which would've happened eventually. By season 9, they really didn't need any more characters, especially working in the office.
