Lois makes Peter do a menial task.
Peter does it for a while but can’t make any progress.
He looks up and says: “this is worse than trying to sleep with 2 blankets!”
cutaway
The camera is aimed downwards at peter in his bed at night.
He has two blankets on but the top one isn’t covering his left half.
He shifts to the right but that only pushes the top blanket more rightward.
He shifts again and it only gets worse.
He then lifts up the top blanket and puts it down on him.
Now the blanket is missing his right half.
Repeat variations on this, the joke is that the cutaway is going for too long.
