100 years of solitude, 100 years of solitude! Take one down, pass it around, 99 years of solitude!
|— Joel, Crow, Servo|

- This film was sponsored by C.G. Conn, a maker of musical instruments, thus the importance of a brand expressed towards the end of the short.
- The short was released on the appropriately titled Mr. B's Lost Shorts??!! by BBI on VHS and by Rhino Entertainment on DVD re-titled as Mr. B's Lost Shorts, part of The Mystery Science Theater 3000 Collection, Volume 6.

A mysterious series of food-truck robberies makes government officials doubt that the 60-foot tall Colossal Man is dead. He is discovered in a desolate mountain range in Mexico, insane and horribly disfigured. The military drugs him and transports him back to America, where he promptly escapes and wreaks havoc on a city. 
- This episode is the origin of the riff "Glen was fifty feet tall!" It's pointed out by his sister, as if it was believed they were trying to find a normal-sized man.
- In The Amazing Colossal Man, it is stressed that Glenn’s fiancée being the only ‘family’ that he has. However, in this sequel Glenn has a sister. The fiancée and the sister are not played by the same actress, and the sister is not meant to be the same character as the fiancée, though they look alike.
- In this film, Glenn Manning is played by Duncan “Dean” Parkin. Glenn’s grunts and groans were performed by Paul Frees.
