Funny / Godzilla (1954)

• At some point in his rampage, Godzilla enters Ginza and sets it on fire. Along the way, he encounters the Wako Main Building and its clock tower, and as it begins to strike eleven, he roars at it before knocking it down completely, as if he was annoyed by the sound it made. Although unintentional, this bit can be considered pretty humorous in an otherwise nightmarish event.
• Emiko and Ogata's relationship is so painfully obvious, you can tell Dr. Serizawa is just waiting for her to officially break off their engagement. When they come to him to talk about something else entirely (the Oxygen Destroyer), he's genuinely surprised.
