I dont get it

you DON'T??

no

the duck walked up to the lemonade stand and he said to the man running the stand
"Hey!"
*bom bom bom*
"Got any grapes?"

what does that mean

you are missing a core part of your childhood
look up "the duck song"

the duck

"I was born yesterday" ahh

but the duck, with complete and utter disregard for both biology and the market system, requests grapes

This most obviously shocks the man behind the lemonade stand, yet he calmy tries to advertise his lemonade, the only object he could sell, to the duck. Much to his dismay the duck declines his offer and waddles off.

in an act of persistence and rebellion, the duck returns the very next day, causing the businessman disdain

That’s it if you don’t stop going to this lemonade stand and ask for grapes I’ll cook you into a five star meal, so don’t get to close

but the strangely enough sapient semi-aquatic avian disobeyed the instructions of the vendor and begged him for that specific fruit.

but does the store have any lemonade?
