Pappu goes to a doctor and is complaining about penis erection problem.
Doc tells him about new surgical breakthrough where muscle from elephant's trunk is transplanted to the penis.
Pappu undergoes the surgery. Few days later he is having dinner with a beautiful date. He gets horny and has to open the zip to relieve the pressure. Suddenly the penis shows up on the table and grabs an apple and goes back into his pants.
Pappu's date is shocked and asks if he can do it again. To which he replies, "Sure I can, but I am not sure my ass can handle another apple right now.
