He Hates Sarah Marshall

As some of you know I practically watch no TV (since we moved to CA, from practically it's turned into none). So, understandably, I was confused by this sign in San Francisco that we ran into as we were getting into the city yesterday:



I guess this could very well be a publicity stunt for Sarah Marshall or could it be the blog of a guy who claims he "was going to dump Sarah Marshall" but she beat him to the punch. I am leaning more towards the first case... otherwise this guy probably deserved getting dumped for being willing to spend so much money on a sign! :)
