One little hatchling has taken this joke phase in stride.
He loves all his older siblings jokes. He is always ready with a smile, and a laugh.
Hatchling no2 - 'Why did the Roman's build straight roads?
Hatchling no5 - 'Goooooba!
Hatchling no2 - 'So they wouldn't drive their soldiers around the bend!'
Told ya he was a great audience. I ought to rent him out to aspiring comedians who need to build their confidence.
