When the heroes set off every alarm in town, there's a brief shot of a man trying to decide which of his helmets to put on: fireman or air raid warden.
When you watch that doctor... first he pokes around and does nothing while the poor old man is getting eaten alive, and then he abandons his poor nurse in a room with the Blob — when he knows just how dangerous it is! What an Idiot! When he gets eaten it's graveyard humor at its finest.
There's a large number of funny lines in this film.
"Wait a minute...hockey season ended months ago!"
The bit of Gallows Humor from Flagg after they try and fail to blow up the blob.
