For example, the "couples counseling" clips for Bones:
Couples counseling 1
Death in the Saddle
Widow's Son the Windshield
The Secret in the Soil
Soccer Mom in the Mini-Van
Honestly, why aren't they married and doing it like bunnies like everyday?
Clips for Huddy (House/ Cuddy; my apologies, Elessar):
In the beginning
How Wilson knows House likes Cuddy
I know why they aren't married and yadda yadda, but still stings

The entire relationship of Chuck and Sarah (from "chuck") with TONS of spoilers:
Chuck Sarah Emotional Roller Coaster Ride Part1
Chuck Sarah Emotional Roller Coaster Ride Part2
And this is just cute Chuck Sarah Kisses and a shower (again, spoilers.)
Again, why aren't they married and doing it EVERYDAY?!
I've found this for Jack and Kate from Lost: Jate Scenes Top 40 (*cough,cough* spoilers and it doesn't have much sense without watching the show.)
I haven't found anything like a selection of scenes for TnT, the only thing I could find is this: Trip/T'Pol - Too Much Love Will Kill You (by the way, the song choice, perfect.)
