The Petersen Automotive Museum is apparently only incidentally paying tribute to Harold Ramis with a giant inflatable Stay Puft Marshmallow Man on its roof today. A rep told us that the Ghostbusters' Ecto-1 Cadillac is temporarily on display in the museum's Hollywood Gallery, but denied there was a huge inflatable marshmallow man on the roof. After insisting we had reliable photo evidence, he made a few calls and said Stay Puft was just being tested out yesterday, but that he could come back in the future. Still, this photo was taken just this morning by a tipster who works across the street and says the marshmallow man is still there. He stays puft even when toasted, apparently. Updated 2:27: Ok so this is an intentional Ramis tribute. Our Petersen-adjacent tipster tells us that a banner's been added that says "You came, you saw, you kicked its ass/Thank you Harold Ramis."
