user21325: Is there any way to take knight and save rook at same time?
Please do tell name, so I can search on YouTube.

user20721: The knight is not sacrificed. If black takes it then he will regret it. The best is to lose the rook and have a bad position.
To answer the other half of your question: Ke7 saves the rook but leads to a terrible position.
After QxP+, black has to play Kf7, then white moves Bc4+. It's all downhill from there until Black is mated.

user307: The opening you are after is Damiano Defense: 1.e5 e4 2.Nf3 f6.
Note that after 3. Nxf3 fe? is a mistake, 3...Qe7 keeps the material equal. There is no way to take the knight and save the rook as far as I know.

user19877: As Akavall said correctly, it is the Damiano Defense, and is named after Pedro Damiano (1480–1544).
Since he answered the basic question about the name, I would not normally, but there is an additional part to the question, so I am going to add that 2...f6? is virtually a forced loss, no matter how you play it, and here is the analysis. So, no you cannot take the knight, and save the rook, or worse happens.
