The cashier says, “No.”
The blonde leaves the store.
The next day, the blonde walks back into the store and says “Can I have that TV?”
The cashier says “No,” so the blonde leaves the store.
The next day the blonde walks back into the store and says “Can I have that TV?”
The cashier says “no” again
This time the blonde asks, “Why won’t you sell me the TV?”
The cashier says “Because, that’s a toaster, not a TV.”
