What is a good YouTube/Minecraft username?

I'm needing a new Minecraft username and don't know what to do. I want it to start with the letters M or L and be similar to the following:
Markiplier
Lachlan

Dude, just DON't start a Minecraft Youtube channel, there are way too many of those already and you will not stick out above the already successful ones. Try something else.
