Inconsistences/continuity errors and/or goofs/oddities
- The Time Dimension not only caught the Yogi Yahooeys, but Scooby and Shaggy as well.
- This story is the first time that Fred Flintstone heard of the Laff-a-Lympics. All of his other visits, seen in the TV series, must be later in time, for him. (Due to time travel, some of them may have been earlier in the Laff-A-Lympics season as seen from the audience's point-of-view).
