One guy visited the doctor and asked for Smarter Medicine,
The doctor prescribed some medicine to him and asked him to come back next week,
When he came back and complaint that he wasn’t getting any smarter,
The doctor offered him the same medicine and again asked him to come back for a revisit after one week,
One week later, the guy sit in front of the doctor and started the conversation directly,
“I know I am not getting smarter, but I just want to know whether the medicine you gave me is sugar or not?”
“Finally,” the doctor said, “you are getting kind of smarter”.
