I don't get it

On the way to a softball game tonight, the kids were taking turns telling jokes.  First there was the knock-knock jokes.  Then came the chicken crossing the road jokes.  And then came the corny jokes like

"How do you make a tissue dance?  You put a little boogie in it."

It was Bree's turn.  She asked:

 

"What animal don't you want to play cards with?"

 

Without hesitation, without missing a beat, like it was poised there on the tip of his tongue Jacob replies..

 

"A hungry duck."

 

Ummmm..... what?  Like.... what?!

 

He'll play cards with a lion or a hippo or a rhinoceros but a hungry duck? 

The line is drawn there. 

I don't get it either, Bree.



FYI:  The answer is...  You never want to play cards with a 'cheetah'.
