My Little Comedians

Zack, Austin (They put there arms around each other without any prompting from me)

The last week Zack and Austin have really been getting in to knock-knock jokes. Usually Zack comes up with them and then Austin repeats them right after Zack acting like he is the one that came up with them. It's so funny to me how clever they think they are. Here are a couple for your enjoyment:
Knock, Knock
Who's there?
Dinosaur
Dinosaur who?
Dinosaur Dragon

Knock, Knock
Who's there?
Dragon
Dragon who?
Dragon Snowflake

I know you're all in stitches now. :)
