David Hasselhoff and the Berlin Wall
This video of David Hasselhoff singing on the Berlin Wall on New Year's Eve 1989, roughly two months after Berliners started tearing down the wall, is amazing. The Hoff's jacket is also amazing, as is his piano key scarf. I think the title of the song he's singing is "Looking for Freedom" or something like that. This goes a long way in explaining why the Germans love the Hoff.
Also, this BBC article is titled "Did David Hasselhoff really help end the Cold War?"
Also, pretty much any video of David Hasselhoff singing on YouTube is amazing, but the Berlin Wall one is especially amazing.
