What do these episodes all have in common?

Cat Out of the Bag
Beaver’s Guest (Larry stayed overnight)
Beaver’s Monkey
Haunted House
Three Boys and a Burro
Happy Weekend
and let’s also add
Beaver Takes a Drive

Boy this one is tough. I see several with animals, but a couple that don't seem to have animals (Guest and Drive). Don't know if you can think of any hints...

Here’s a good hint: Nighttime/early morning
Haunted House has a scene at the very start that fits the category

Answer: In all these episodes Ward and June or just Ward are woken up in the middle of the night for a sick Larry, a burro on the loose, a nightmare, a monkey, a cat in a tree and when the boys are too loud at night. Also an early wake up so they can wash the car in Beaver Takes a Drive. I should have mentioned Beaver and Henry as Ward is woken up when the trap catches the rabbit.

Name the only time Ward and June wake up Wally from a sound sleep at night.

Easier: the one where Gilbert stays over: the boys gets scared by Lumpy in his car in his costume (this sounds like a Beaver essay), and call the police and get Lumpy and Scott or Bill Scott arrested. W & J wake up Wally and June stupidly asks if he has any idea who might know something about it (news flash: you should know your own kid by now!)

That’s right “You mean your brother, Beaver?” What a stupid thing to say!!

Wally could have said - "Who else?" like he did when Beaver was rescued from the soup billboard.

That’s right “You mean your brother, Beaver?” What a stupid thing to say!!

"No, my brother Platypus."

"No, my brother Platypus."

:lol:

I should have added A Horse Named Nick as the boys wake up Ward and June really early.
