So I'm driving along in the rain when my two girls start telling each other knock-knock jokes. The only thing is, Gloria is 3 1/2 and Diana is 2, so they only kinda get it. This is what I hear:

G: Knock Knock
D: Who's there?
G: Orange
D: Orange who?
G: Orange you glad I didn't say strawberry
(they laugh)

then

D: Knock Knock
G: Who's there?
D: Lacka lacka
G: Lacka lacka who?
D: Strawberry
(they laugh)

and then finally, this gem:

D: Knock Knock
G: Who's there?
D: Strawberry
G: Strawberry who?
D: Nana loves you Gora!
(Nana= Diana and Gora = Gloria)

Even I laughed at that one.
