This seems to be a bit of a tradition for Gameday week. I think we've had sign threads for every CGD that has been in Ann Arbor, so... whatcha got? I won't be there so I'm just here to submit bad ideas and dated dad jokes.
Maybe a bald head and goatee photoshopped on Harbaugh - "I AM THE ONE WHO KNOCKS"
"Worst day for Spartans since Thermopylae"
Like I said, I'm just here to suggest bad ideas.
EDIT: I see that I've committed an MGoSin. I maintain that there is enough content coming in to keep this thread up, double post or not.
