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?"
"Design for Dreaming" was also included with the limited edition Shorts, Volume 3. "Are You Ready for Marriage?" label-jumped onto Shout! Factory by being also included with its original episode Racket Girls on Volume XV.
