Continuing from "Up All Night", Dag and Norb return to the present and then attempt to go to sleep, but realize that they're too tired to sleep. As a result, yet more mayhem than the previous episode, such as sheep taking over the house and hallucinations, ensues. When Dag and Norb finally fall asleep, not only do they sleep so long that they become elders, but the sheep take over the entire world.
- Norb and Dag wake up in the same futuristic world from "Up All Night," but this time it's overpopulated by sheep and Norb and Dag are now elderly beavers, since they slept.
- This aired nearly two years after it's prequel aired.
- Second episode to use live action footage. 
- Star Wars - In the beginning of the episode, the description of the episode rolls up screen. This is a spoof on the epic space opera film series, which the description of the movies rolls up screen.
- Doctor Who - The time/space traveling outhouse that brings Norb and Dag back to the present may be a reference to the TARDIS.
