Crackin' Up at Knock Knock Jokes

"Grandpa,
you ancient
and wrinkled
fool, do you
know who
these guys
are?"
"Well my
little MiniMo
...that would
be Ethan up
in front, his
dad - Uncle
Ron that's
holding you and Uncle Nelly holding down the back.
And somebody with a giant green ring got her hand
on Ethan's shoulder. I hope she won't get carpal tunnel.
It looks like everybody's cracking up at something.
Did Ethan tell you the famous Hawaii knock-knock joke?"
"No...what's the famous Hawaii knock-knock joke?"
"Well, it's not even really that funny....here it goes.....
Knock knock...who's there?...Me Ma.....Me Ma who?..."
"Grandfool, is that the joke? That's sadly un-funny."
"Yeah, well if you've had a few beers...it's hilarious."
"Grandknucklehead...what's the best knock-knock
joke you ever heard?"
"Well, I have to warn you first...my sense of funny
isn't probably gonna be your sense of funny.....
But here goes....
Tell somebody, 'Knock knock'...and then when they say
'Who's there?'...just turn around and walk away."
"Grandpa, did you fall on your head when you was small?"
