I am never forget the day I first meet the great Lobachevsky.
In one word he told me secret of success in mathematics: Plagiarize!
Plagiarize,
Let no one else's work evade your eyes,
Remember why the good Lord made your eyes,
So don't shade your eyes,
But plagiarize, plagiarize, plagiarize...
Only be sure always to call it please "research".

"Lobachevsky". - Songs by Tom Lehrer (1953)
