One Thing by Finger Eleven. I think this song single handedly finished off grunge/alt rock by being so incredibly awful. This is the song the frat boy listens to after he finds out that his tri-delt girlfriend has been getting plowed on the side by her old HS boyfriend before going out to a bar and hooking up with some rando townie.
This song actually has the following line:
Even though I know
I don't wanna know
And it is repeated several times.
The video is the icing on the cake with the white guy dreadlocked drummer faking playing the timpani for dramatic effect.
