1. 8x02 Plastique: Clark was the one that deduced that Tommy wasn't the one that caused the blasts based on his autopsy.
2. 8x05 Committed: Clark came up with a smart plan to not only knock out the bad guy, get the Kryptonite out of the room, and save Lois without her seeing him use his powers.
3. 8x06 Prey: Though his methods were questionable, Clark was actually right about both killers.
4. 8x07 Identity: Clark came up with way to get Jimmy off his scent...yeah, he abandoned it to save Lois, but that made him even more awesome. Saving a life was worth more than his secret.
5. 8x11 Legion: Clark was the one that came up with a way to get rid of Brainiac without taking any lives.
6. 8x15 Infamous: Clark not only used the Legion Flight Ring to turn back time, but he had enough foresight to write his own story about Linda Lake to discredit anything she would say in the future.
7. 8x16 Turbulence: Although Tess was a step ahead of him, Clark came up with a way to save them from the plane without her seeing and came up with what could have been a convincing lie as to how they escaped.
8. 8x17 Hex: Clark was able to talk Zatanna out of her plan to resurrect her father by relating his own loss of a parent.
9. 8x20 Beast: Clark came up with a way to take care of Davis without taking a life. It was his "friends" that kept the plan from coming to fruition (by using emotional blackmail, I might add).
10. 8x21 Injustice: And once again, Clark came up with a NEW EVEN BETTER way to save Davis by separating him from Doomsday, and STILL send Doomsday to the Phantom Zone...once again, his plans were halted by others.
Bonus Points
8x12 Bulletproof: It was Clark's influence, though it came out of Oliver's mouth, that helped Dan Turpin do the right thing.
Do you have any other examples so we can stamp out this stupid epitaph once and for all?
