Mr. B's Lost Shorts is a compilation of shorts from Mystery Science Theater 3000. Originally released exclusively on VHS through the MST3K Info Club, it was later re-packaged with Rhino Entertainment's Volume 6 box set in October of 2004. There were six shorts included.
The "Mr. B" of the title is, of course, the titular Mr. B Natural. It is probably for this reason that this is the only shorts collection where the shorts are not organized in their original chronological order of release.
- "Mr. B Natural"
- "X Marks the Spot"
- "Hired, Part 1"
- "Design for Dreaming"
- "Johnny at the Fair"
- "Are You Ready for Marriage?"
"Mr. B Natural" is the only short in the collection not to have any other release. "Design for Dreaming" was also included with the limited edition Shorts, Volume 3, and all the others have been released on DVD as part of their respective episodes.
