There are some human activities that are univeral. Everyone eats and sleeps.
Beetle Bailey is a champion snoozer. He takes advantage of any opportunity to take a nap. He stays in the sack late in the morning and goes to bed as early as he can. He falls asleep quickly and is impossible to wake up.
In the Sunday page above, from September 24, 1989, Sarge observes how everyone in the barracks has a different way of sleeping. Beetle, of course, does what he does best.
Below is a similar gag from 2009. Sarge seems unaware that he has the strangest sleeping habits.
People also dream when they sleep. In this episode from 2015, General Halftrack, Lt. Fuzz, Zero, Killer and Sarge all have dreams that reveal something about their character. Beetle just dreams about dreaming. That's as deep as he gets.
I hope this post didn't put anyone to sleep. It's time for my nap.
