A corporal took a company for an excursion to the zoo.

The corporal:

“And this is an enclosure with giraffes. But now they are not visible, as they are hatching out eggs in their nests.”

A soldier:

“Sir, but giraffes don’t hatch out eggs!”

The corporal:

“What?! 8-((( 40 curtseys!!!”

[ The soldier curtseys]

The corporal:

“So what have you asked?”

The soldier (choking):

“And when do they fly to the south ?”
