How to avoid scholar's mate?

So I was playing a chess game, and some cheapskape decided to use the scholar's mate. I completly lost to him. For those of you not familiar, scholars mate is a 4-turn check mate that either looks like:

Another example would look like this:

I know what scholar's mate is, I just don't know how to counter it when I'm black. Can someone give me a list of counters for each example. Any help will be greatly appreciated.

A knight on f6 and a pawn on e6 will stop them, and be decent moves (i think)!

Generally people play the Queen first to h5 if so Nc6 followed by g6 and then Nf6

If Bc4 first try to transpose Nc6 first if Qf3 Nf6 and if Qh5 g6

Ok.

First, some comedy. Head to this link to see a grandmaster get checkmated with the Scholar's Mate.

Now let's get serious.

For the first example, do Nf6. That will block the queen's path.

For the second example, g6 is an adequate response. It 50% of the time transposes into the first example, and I already told you how to counter that. Usually a player will play the Queen first. An example: (This means hungry_girl's comment underneath WILL NOT be useful.)

Hope this helps!
The top answers are not the main ways or are just confusing to me.

Looking at your examples.. playing nf6 before nc6 would prevent scholars. I think most people tend to play nf6 first anyway to allow castling earlier?

I also lost to this recently. I don't do well against "berserkers" - those who bring out their queen early and go for a quick cheap mate. I wonder if there are any books about how to avoid cheap mates??

Check this book out so YOU can be the one to do quick cheap mates: Quick Chess Knockouts. 

You can say I am a turned chessstar after reading that book (but I don't usually do these mates)
