Policeman:”What are you selling?”
Vendor:” Apple seeds… $5 a pop!”
Policeman:”What???Why would anyone want to eat apple seed?”
Vendor:” They make you smarter!”
Policeman:” OK, give me one (swallows it)… wait a minute? For $5 I could have bought a pound of apples and got myself at least 20 seeds!”
Vendor:” See!!! You’re smarter already!”
Policeman:” WOW, you’re right… Give me two more, quick!”
