"This Afternoon" was recorded in 2008, and the video you're about to see came out two years later.
Now, most colleges start before Labor Day, so this qualifies as a "Video of Summer". Nickelback is, well, conscripted to play a frat party. Enough said.
Unfortunately, "This Afternoon" peaked at #34 on the Hot 100, but fared better overseas. Go figure, right?
