Gettin' Swayze

I'm trying to figure out what's the best part of this 1979 commercial. Is it the fact that it features Patrick Swayze? Is it the song? Swayze's hair? The fact that it's for Pabst Blue Ribbon, yet features stylish "cool" (relative to the year) people? The dancing? ...It's gotta be the dancing, right? But then again, there's also the fact that it's a full minute long, twice the length of most ads.

Maybe, just maybe, it's the combination of all of those factors.
