Knock Knock jokes are big here in our house. Hope is just started to get them, and loves a good round of knock knock jokes. Noah, wanting to be a part of the fun, tries to participate as well. He says this knock knock joke no less than 20 times a day. And it cracks himself up every single time.
Noah: Knock Knock
Us: Who's there?
Noah: 'nana popsicle
Us: 'nana popsicle who?
Noah: 'nana popsicle!!!
Followed by a pause until someone laughs, and then he cracks up.
Yeah, we don't get it either. :) But, he sure is cute.
