Actual knock-knock joke our preschooler told at dinner a couple weeks ago (with our responses):

Knock-knock

Banana
(Banana who?)

Knock-knock
(Who's there?)

Banana
(Banana who?)

Knock-knock
(Who's there?)

Pickle
(Pickle who?)

Pickle you glad I didn't say "Banana"! [Cackles with laughter]

Happy National Pickle Day.
