In Israel the Blonde jokes are all about Kurdim…and I have to admit that it tends to be very true…so place your “not smart person” term in the following joke as you prefer:
A “person” is shopping around the grocery store, when he notices an odd, almost futuristic looking object on the shelf. Calling over a clerk, he asks him to explain what it is.
“That,” says the clerk, “is a Thermos cup!”
“Woooow….that sounds awesome! What does it do??”
“Well,” explains the clerk, “that keeps hot things hot, and cold things cold..!”
Impressed with the prospects of such an invention, the “person” buys two of them.
Later that week, he’s at work, holding his Thermos cup in hand and feeling like the king of the world, legs up on the desk and everything. Along passes the boss when he notices his employee with a strange looking cup on his desk. “what’s that?” he inquires.
“This,” the “person” answers smugly, “is a Thermos cup. It keeps hot things hot and cold things cold!”
“Oh! Sounds really cool! And what, if you don’t mind me asking, do you have in their at the moment?”
The “person’s” smug smile turns even wider. “Coffee and two popsicles!”
