This is an awesome(probably not very famous) one liner in hindi on engineers. I could not stop myself: Aamir Sarfraz (aamir rajput khan)

"Chaar saal lagte hai insaan ko engineer banne mein phir chahe wo puri zindgi laga rahe dubara insaan nahi ban sakta"

Translation in English:
"It takes four years for a uman to become engineer after that even if he tries for whole life he can't become human again
